Do we need Christian unity?

It is great to be with you today and to share with you some thoughts on the theme: Do we need Church unity? I recognize that we come from different parts of the world where our experiences of Christianity and church life may be very different bearing in mind various contextual and cultural experiences. Yet, universally Christian’s ought to reflect on their life together in the world and on what they have to say and do to make the world a better place for all people and creation.
I trust that your time together thus far has been very enlightening, engaging, challenging and an opportunity for new encounters of learning and exposures. Above all, I hope it is deepening, broadening and developing your theological thinking and spirituality. If theology is faith seeking understanding, then we need to interpret theology in contextually lived- experiences of real-life encounters.
We live in a time when faith is in crisis. A time in which many people do not see the necessity to believe in God or even if they do, they don`t seem to practice their faith in meaningful and devoted ways. This is perhaps because of disillusionment, inability to understand God and what is happening in the world today, or a pure sense of disbelief and attractions to the rising secularization of society and growing atheism. Social scientists have for long predicted that we are heading into a religion less age, but they are wrong. Research tells us today that some people are not interested in religion per se, but they focus on God and spirituality. They are given to more eastern forms of spiritualities that stress mystical experiences and out of body encounters to cope with the challenges of life.
In such a context Christian unity matter. However, we need to ask a new set of questions to be relevant, provide meaning and answers to pressing questions and needs. Without changing the substance of our faith, we must engage new styles and ways of reaching people with the gospel of Christ, especially the young people. We are so wrong when we think that young people are not interested in God. Again, research shows us that they are not interested in the Church or organised religion per se, but they are certainly keen about God. I look at my own children and see a depth of spirituality that I did not have even though I went to church almost every Sunday and most weekdays. My view was an absolute and unquestionable devotion to form and practice of faith, this is what you did if you believed in God in the time when I was growing up. But today most young people seek critical engagement with reality and God.
Albert Einstein`s secretary once asked him why he always asked the same questions. To which he replied, “because I have new answers.”. This is something Christian leaders must think about seriously. Why? Because Christianity matters. So, let us now ask the question, “Do we need church unity?”
In 1948 when the WCC was established, it came together to proclaim Jesus Christ to the world together. There was a clear belief that church unity matters. We said emphatically that we need church unity for essentially two (2) primary reasons that can be summarised in two words: Word and Witness.
Firstly, scriptures reflect on the calling for Christian and church unity.
The Apostle Paul speaks very strongly about Christian unity in Ephesians 4. He implores us to “make every effort to keep the unity of the Spirit through the bond of peace.” He then proceeds to remind us that “There is one body and one Spirit –just as you were called to one hope when you were called – one Lord, one faith, one baptism; one God and Father of all, who is over all and through all and in all.”
The Apostle in these verses reminds us that we are called to unity. Unity is God`s gift to us. Unity is not uniformity but oneness and togetherness as we proclaim Jesus Christ to the world. A broken and divided church does not have a message to an already broken and divided world, especially if it does not exemplify and practise what it preaches.
The Apostle Paul in verses 2 and 3 speaks of the character that works towards unity. He says: “Be completely humble and gentle”, note not partially but completely. “Be patient, bearing with one another in love.” These are the characteristics that enable us to keep the unity and remain faithful to our calling to unity. When we listen to God then we learn to listen to each other as we share God`s message with grace and truth. It is not always easy because we each think that we are listening to God and yet we come up with different messages. The spirit in which we listen to one another is important. Paul tells us that it must be with humility, gentleness, patience and love.
Admittedly, every family has its challenges with disagreements, likes, views, preferences and desires but they are still a family. The church is no different. Therefore, at all costs we must make every effort to keep the unity of the Spirit through the bond of peace, says the Apostle Paul. Christian unity matters!
My Church in South Africa, the Uniting Presbyterian Church in Southern Africa, came into a union of two churches in 1999. Unfortunately, two years later the Union faced serious challenges. At the Union, eight Associations for Women, Men, Youth and Young Women joined to become four. However, it soon became apparent that it was not working. This then led to the establishment of another four groups going back to the original eight. The problem was that you had a Union in theory but not in practise. The UPCSA appointed me to bring the eight Associations back into four. This was a rather difficult task, impossible by the conclusions of many. To cut a long story short, after 15 long years the eight Associations became four again in 2019. It was a miracle! The unity of the church was restored. All things are possible with God!
History has shown us that the church is not always where God wants it to be. For example, we see this in the message to the churches in the Book of Revelations where they receive strong rebukes from God. From time to time, the church may need rebuke, renewal, revitalisation, transformation, and even repentance, faithful witness requires this, but never at the expense of its unity. What brings us to such a conclusion?
Jesus prayed for the unity of believers in John 17. I know that while many people continue to yearn, pray and work for visible Christian unity some have become disenchanted and despondent on the journey, believing that such is a far fetch dream and further from reality as we encounter many challenges. Too many churches today are giving into splits and fragmentation on grounds of doctrine, theology, socio-ethical issues, money and personalities. Some say, “We can never have unity or be in the same church anymore because we have such great differences, especially these days on the issue of human sexuality or the ordination of women.
This, of course, can be a huge issue for the WCC with our 356 member churches, you can imagine how polarised we can be on this issue. In June 2022, at the WCC central committee the issue of human sexuality caused immense debate on the subject so much so that the Council`s unity stood in question. Then a miracle moment happened when we adjourned and asked some people with opposing views to come up with a solution. By God`s grace and wisdom, they did. It is a clear indication that we can have church unity despite our differences.
Personally, I believe that we must never stop praying and walking and working together for Christian and church unity. We need to affirm and deepen the desire for Christian unity knowing that this is what Jesus prayed for in John 17:21. Unity is a GIFT already given to us to appropriate in Christ, unity is not uniformity and, more so, a broken and suffering world needs Christians working together towards reconciliation, justice and peace. Our inability to live up to the calling of visible Christian unity should not diminish or blur the ultimate vision. We must continue to pray and work together so that the world may believe! Whatever the challenges we may face in preserving the unity of fellowship as Christians we must not fixate on what separates us but on Christ who unites us and calls us to have unity in our witness to the world. Christian unity matters!
Whether we understand unity as spiritual, relational, organic or common purpose, what matters most is that we are called to pray, walk and witness together so that the world may believe that Jesus is the Christ, the son of the living God and in believing in Him they may have eternal life.
Christian unity is a gift from God; in the death and resurrection of Jesus we have been reconciled and made one. In Christ all walls and barriers of hostility are broken down. It is sad that as Christians we have not often comprehended, understood or lived this grace nor do we live graciously. We tend to emphasise what differentiates us rather than what unites us. The Scriptures is clear; it is Christ who make us one. The document on the Joint Declaration on Doctrine of Justification by Faith illustrates this.
Christian unity is also about the GRACE of God. In not sparing the life of Jesus, God`s only begotten Son, we have seen and received the abundant grace of God. It is this grace that calls us to be inviting of others, to be hospitable, to show mercy, love and compassion.
Our unity is a witness to the world. That is the second point that emerged from the founding of the WCC in 1948. We learn in John 17 that Christian unity is for the GLORY of God as Christians witness together to the world. So that the world may believe. When Christians pray, walk and work together God is glorified. The Council said this after facing the aftermath of the second world war, it called for Christians to witness and work together for peace in the world.
Well, the world has not changed much since then. In fact, if the truth be told, it looks worse. Let`s look at the global context to gain a bigger picture. In this we can also sense the need for church unity today.
Our Context: All Creation Is Groaning
As you know, we are living in very difficult times. The current global context has been described as a “poly-crisis”. Multiple threats — such as accelerating climate change, COVID-19 and its impacts, injustices, poverty, diseases and health challenges, conflicts and wars, unprecedented levels of forced displacement, migration, increasing hunger and food insecurity, rising inequality and marginalization, and widespread economic instability among others — are converging in complex inter-relationships. The WCC 11th Assembly captured this well:
“We live and witness in a world which is at the same time God’s beautiful creation and broken by ecological crisis, war, pandemic, systemic poverty, racism, gender-based violence, human rights violations, and many other sufferings”.
The largest context and most pressing challenge for today’s ecumenical movement is the state of the oikoumene, the “whole inhabited world.” Today we live in difficult, even perilous, times, a time of crisis. Ourcurrent global context has been described by our most recent assembly as a “polycrisis.” Five immense crises are, in our day, converging:
(1) Accelerating climate change threatens lives and livelihoods, wreaking havoc and even causing the extinction of species.
(2) Increasing economic inequality, the result of an unjust economic order, has left billions in poverty and stifled progress toward food security and global healthcare.
(3) We are also witnessing a worldwide recession from the longheld consensus about human rights, threatening the dignity and legal status of religious and ethnic and sexual minorities.
(4) Likewise, we are recently undergoing a crisis of governance, through a retreat from and paralysis of democratic institutions, an advance of authoritarian regimes, the impotence of our international institutions to secure peace and well-being, the rise of mis- and disinformation in politics and media, stoking societal tensions and xenophobia.
(5) And finally, and most painfully, we are experiencing widespread and frequent outbreaks of violence within countries and war between them.
Today’s terrible and unnecessary wars are symptomatic of the whole polycrisis. We all know about Ukraine and Russia, and, since 7 October, the war between Israel and Hamas (a conflict with roots that go back to 1967 and even 1948). But there are dozens more wars and conflicts going on that don`t get much coverage.
These global trends, each of which engenders incalculable human suffering, are the broadest context in which Christians and Christian churches are living their ecumenical fellowship today. Their scale is global, their peril imminent, their solutions uncertain. They threaten the integrity of life on earth as we know it. As theApostle Paul says in Romans 8:22-24, “the whole creation has been groaning in labour pains.”
In such a global and local context, we ask why Christianity unity matters. Allow me to offer some answers. The WCC speaks of a Pilgrimage of Justice, Reconciliation and Unity. A pilgrimage is an invitation, a direction and a methodology. As Christians we are people of the way, we are also on the way. We are on a journey together, trusting the Holy Spirit to lead us and expecting God to surprise us. I would like to use this idea of a pilgrimage as a basis to answer this question, do we need church unity? I would like to argue that we need church unity for the following:
PROCLAIM GOD`S JUSTICE
The cry for freedom and justice is loud for many in the world today. We are surrounded by the need for economic, gender and climate justice. God uses a number of instruments to reach and transform the world, including and especially the church. Therefore, the church needs to hear and respond to this painful cry. The mission of the church is to follow in the footsteps of proclaiming Christ’s love to the world. The church needs to stand where God stands and not get mixed up with the rich and powerful. Justice is best expressed in standing up for truth, siding with the poor and holding out hope amid injustices and sufferings.
The God portrayed in Scripture is the “lover of justice”: He calls us to do justice, love kindness and to walk humbly with him” (Micah 6:8). The task of the Church is to maintain a consistent prophetic voice against injustices. In the face of unjust economic systems, increasing poverty, unnecessary wars, ethnic and racial violence we need to say enough is enough. Our cry for justice must be loud, clear and prophetic. However, to do this well we need to first address injustices in the church – economic, gender, youth, digital and ecological injustices. The God of justice calls us to stand up for justice and to live justly and to love mercy. Where is mercy when thousands of people are killed in Palestine, Ukraine, Sudan and other parts of the world? Where is justice when thousands of people go to bed hungry every night? Where is justice when thousands of people are denied access to humanitarian aid? Where is justice when hundreds of migrants drown or die while fleeing their countries? Where is justice when human rights and dignity are denied, deprived and violated? Where is justice when indigenous people are denied of their rights, land and history? Where is justice when old people are forgotten, and young people not given space to express themselves?
The God of justice and mercy calls us to stand up for justice. We cannot be silent. Christians need to stand up for justice, and we need to stand together. In unity is our strength. We are better and stronger together. Together we can shout. “Let justice roll down like waters, and righteousness like an ever-flowing stream” (Amos 5:24). Together we can make a difference in the world. Together we can live and fulfil God`s vision for the world. Together we can say Christianity matters.
Proclaim Love and Reconciliation
Christianity matters because it is a gospel of love and reconciliation. With all the suffering and pain in the world today, what the world needs is love. Properly understood and if practiced well the Christian faith is the message of love. John 3:16 tells us that “For God so loved the world that he gave his only begotten son.” God is love and those who love God must love others (1John 3:11-15). We live in a world full of hatred, we hear hate speeches and witness racial and ethnic conflicts in so many different places.
There is so much of brokenness, pain and sufferings in the world. What is the message of the Church in such a context? How do we work towards healing, forgiveness and reconciliation?
The Genesis story of the Fall (Genesis 3) tells us that sin separated us from God and left us with doom, destruction, and death. There was no way out. There was absolutely nothing that humans could do to redeem ourselves, save ourselves, and get back into a reconciled relationship with God. The great news is that God’s love refused to leave us there. Instead, God sent his only begotten Son to come into the world to suffer and die for the world, and through his death and resurrection, Jesus saved, forgave, and reconciled us to the Father and to one another, breaking down the walls of hostility and giving us peace.
Consequently, we are reconciled to the Father. God’s forgiveness is all about love. Suffering love! Forgiving love! Reconciling love! We cannot say that we love God and hate our brothers and sisters. The love of God forgives us and prompts us to forgive others and to embrace others who are different from us.
In the South African experience after apartheid, there was the call for forgiveness and reconciliation. The ability of those who have been wronged to forgive their oppressors and offenders is no easy task. Forgiveness is complex. The process of forgiveness is recognising that we cannot change the event itself, but we can change the meaning we give to the event. Thus, victims are often unwilling to let go of the emotional tags associated with the hurt, bitterness, vengefulness, and hatred toward the perpetrators.
Yet, many South Africans did ask for forgiveness, and many others forgave those who violated their rights and human dignity. The Truth and Reconciliation Commission (TRC) with its many failures in meeting its full objectives still provided a facility to help people to face their oppressors and to find healing and forgiveness. Many churches appeared before the TRC and confessed to their own complicity, silence, and part in promoting apartheid in South Africa. It is apparent that forgiveness is important to find reconciliation and healing.
In the quest for reconciliation and unity, forgiveness becomes an essential point of departure. Forgiveness is an important part of reconciliation. You can forgive someone and still refuse to be reconciled with them; but to seek reconciliation, forgiveness is necessary.
There is a need for forgiveness, healing, reconciliation and love in the world. Christians can and must play a significant role in spreading love. The WCC theme at its last Assembly in 2022 was: “Christ`s love moves us to reconciliation and unity.”
Following the example of Christ’s love, churches ought to help people to be brought into spaces to forgive, be forgiven, and seek reconciliation. The love of Christ reconciles a lost and broken world, not only to God but to the whole creational order which is renewed by the sacrifice of Christ. The doctrine of reconciliation is a prominent theme in the New Testament, and the theological essence of the concept is expressed in 2Corinthians 5, which reads:
Therefore, if anyone is in Christ, he/she is a new creation; the old has gone the new has come! All this is from God who reconciled us to himself through Christ and gave us the ministry of reconciliation: that God was reconciling to himself in Christ, not counting men’s sins against them. And he has committed to us the message of reconciliation. We are therefore Christ’s ambassadors, as though God were making his appeal through us. We implore you on Christ’s behalf: Be reconciled to God! (vv.17-21).
In this sense, reconciliation is God’s gift to not only to reconcile fallen humankind with Godself, but also with all humanity and creation.
The church as a reconciled community must display unity, justice, peace and love. The church should not perpetuate human divisions on race, ethnicity, gender, caste etc. Instead, it ought to strive towards reconciliation and unity. If this is the case, then the church needs to articulate reconciliation and unity within its own life and witness so that the world may know the love of Christ. The church must work towards the renewal of all relationships and the restoration of human relationships with creation. As reconciled people, they have to be the proponents of ecological concerns and the precursors of the restoration of the integrity of creation. Christians are called to do good to all people and to love the enemy. They are to be the promoters of peace in society and agents in the formation of a new humanity. The church is called to constantly work towards forgiveness, reconciliation, and unity, bearing in mind its agency in transforming society so that all may have the fullness of life. Forgiveness ought to set the social condition for the process of reconciliation to restore and heal not only interpersonal relationships but also constructively rebalance the political, legal, and economic injustices toward preventing the prospect of renewed conflict.
The WCC has over the years maintained the biblical imperative of reconciliation and unity to heal and restore a broken world. The love of Christ ought to move churches into visible unity, spiritual and social transformation, and justice. Programmes such as combatting racism, justice, peace, and integrity of creation, and in last few years, the Pilgrimage of Justice and Peace, have all indicated the WCC’s endeavour to strive for reconciliation and unity in the world, starting with churches as co-pilgrims on the journey.
I think it fair to say that at the WCC Assembly in 2022, with its emphasis on the love of Christ and its fruits in justice, reconciliation, and unity, the assembly really nurtured “an ecumenism of the heart.” Love, our self-surrender to God in faith and our self-giving to our sisters and brothers in solidarity, is now firmly in the centre of our whole ecumenical endeavour. A deepening, global ecumenical spirituality was voiced in Karlsruhe in more Christocentric tones. As the Unity Statement adopted there proclaimed, “In a world like this, wounded by divisions, the churches are called to witness to the indestructible power of love to bring together and reconcile. Through the faith they proclaim in the gospel of Jesus Christ, the churches are called to bear a counter-cultural witness: the hope of unity, justice, and peace.”
The centrality of love, and our faith in its power to transform the world, was reaffirmed in the assembly’s closing message, entitled “A Call to Act Together”: “We will find a strength to act from a unity founded in Christ’s love, for it enables us to learn the things that make for peace, to transform division into reconciliation, and to work for the healing of our living planet,” and indeed all creation.
PEACE
Christianity unity matters because we proclaim a gospel of peace. We have already mentioned that we live in very troubled times of raging violence, conflicts and wars. There seems to be no peace. Political leaders and countries believe that they can find solutions through violence. They are so mistaken. The WCC speaks against violence and calls for dialogue to resolve problems and conflicts.
The WCC has over the years worked for peace in the world. We spend a great amount of time, energy and money to work for peace. I went to Ukraine and Russia, to Israel and Palestine, Sudan and recently to Colombia where we engaged with church leaders, politicians, presidents and other groups trying to work for peace. It is no easy task. Even churches express different views, we are too caught up in religious nationalism, often used as instruments of states and politicians whether rightly or not, that is not the matter. The truth is that if we are to truly follow Jesus, the Prince of Peace, then we must be peacemakers, peace- builders and peace- keepers. I have seen how churches are in disunity and discord with one another because they are influenced by politics rather than their faith in Jesus Christ. Admittedly, it is difficult to not be influenced by the realities and experiences of our times. But how can we allow God`s Word and Spirit to speak to us and to use us as Christians as instruments of justice, peace and reconciliation that leads us to unity? Christian unity matters, because our Lord calls us to proclaim peace to the world. Yet there can be no peace without justice. Christians are called to work for just peace in the world.
Where are those places in your country that you must work for peace? We must choose to follow Christ rather than our own preferences, prejudices and pride. Blessed are the peacemakers, for they will be called children of God (Matthew 5:9).
HOPE
Christian unity matters because we are a people of hope. Amidst struggle, sufferings and strife, we live in resurrection hope. In the anticipation that all will be well. That justice will come. That love will prevail. That peace will come. That we will be one in Christ in unity. Hope is an eschatological gift for the future but with the resurrection of Jesus, hope breaks into the present. Therefore, we keep hoping but hope is not passive resignation leaving it all to God, it is working with God as instruments to bring in God`s kingdom of justice, righteousness, love and peace. Hope does not disappoint us for God pours out his Spirit into our hearts. Hope is resilience, resistance, protest and transforming witness to the power of Christ to change the world to embed the ideals of God`s justice, peace and love.
The WCC Pilgrimage of Justice, Reconciliation, and Unity reframes our historic commitments—to unity, public witness, and service—to meet head on the existential challenges we face today. This sacred journey, in which churches around the world take up the concrete work of justice and peace, seeks to direct and embody thelife, witness, and programmatic work of the council over the next eight years. It evokes and supports a theology of accompaniment that extends the reach and effectiveness of our ecumenical community, our public commitments, and our collaboration in service. We want to show up where you are. We want to walk and work and pray with you, to learn from you and be present everywhere that there is evident need.
In our Pilgrimage of Justice, Reconciliation, and Unity, we unite our worldwide fellowship of churches not only around our shared Christian faith, which remains our vital centre, but also in the specific interests of justice, love, peace, and hope. That is faith’s imperative and our clear vocation.
A Christian unity that matters must be guided by spirituality, renewal, impact and relevance. We must address the numerous challenges in the world, country and context. Christians must work for justice, love and peace as we proclaim the message of saving grace in the Jesus Christ to a broken and suffering world. Vital Christianity must speak of transformative discipleship, theological renewal, reforming churches, technological and digital integration if we want to reach young people, inspiring worship, relevant liturgy, interreligious dialogue and cooperation, decolonial imperatives, and Christianity unity.
Let me emphasise that Unity is indispensable. As we address the various conflicts and crises in the world, it isimportant for churches to seek unity and to work together. Apart from the fact that Jesus prayed for the unity ofChristians so that the world may believe, global challenges warrant that we work together to heal, reconcile,and restore creation. The Christian voice for unity is not restricted to the church but to the unity of allhumankind and indeed the unity of all creation, and to this end we are called to work with people of other faiths and all people of goodwill who share the same mission. For seventy-seven years, the vision of the WCC hasbeen expressed as a commitment to stay together, pray together, move together, and act together as a fellowship of churches seeking visible unity and common witness. In its “Unity Statement,” the 11th Assemblyinvited the churches to continue that unity:
We affirm the vision of the WCC for the visible unity of all Christians, and we invite otherChristians to share this vision with us. We also invite all people of faith and goodwill to trust,with us, that a different world, a world respectful of the living earth, a world in which everyonehas daily bread and life in abundance, a decolonized world, a more loving, harmonious, just, and peaceful world, is possible. In a world weighed down with so much pain, anguish, and fear, we believe that the love we have seen in Christ brings the liberating possibilities of joy, justice for all,and peace with the earth. Moved by the Holy Spirit, compelled by a vision of unity, we journeyon together, resolved to practice Christ’s love, following his steps as his disciples, and carryinga torch for love in the world, trusting in the promise that Christ’s love moves the world toreconciliation and unity.
It is clear from this statement that church unity is needed to witness to and transform the world as we addressconflicts, divisions, brokenness, and pain. A broken and suffering world needs the unity of churches and Christians. Christian unity is a sign of hope to the world and a vocal testament to the power of love to heal, to reconcile, and to bring peace.
Based on this hope, our public witness and advocacy for peace, justice, and reconciliation present a moral compass and call to conscience for the world. They demonstrate to everyone that life and love will triumph over death and greed. Embodying hope, these are the ways of peace, the ways of righteousness, the ways of living together as human beings sharing the same planet and serving each other as we serve God in the world.
Crucially, we can mobilize the world into seeing there are other ways. The hope that we find in the love of God and in the Resurrected Lord of Life can counter our temptation to disillusion and despair. Church unity is crucial to offer such witness to the world.
Concluding Remarks
Do we need church unity? The answer is a definite yes. The WCC has shown over the years that by Word and Witness we are called as churches to witness and work together to God`s glory and the earths good. `When Christians work and witness together in the world we glorify God and transform the world to be what God intents and desires it to be.
We thank God that the WCC with its 356 member churches are working and witnessing together to shape and transform the world. However, still much must still be done to fulfil the prayer of Jesus that we all be One. While we may retain our different church identities, we must never allow these to become an obstacle or hindrance to our visible Christian unity. We still must address the issues that breed divisions and disunity and separates us at the table of fellowship the sacrament of the Lord`s Supper, Communion, Eucharist or mass but we must always hold Christ in the centre. It is Christ who holds us together. It is Christ who holds the world together in all its brokenness, pain and suffering. The church can stand as a sign, witness and testimony to Christ who holds all things together. In this sense, church unity is not an option but an obligation. It is an imperative and obedience to the prayer of Jesus: “Father, that they maybe One.”
