One Heart One Voice

Twenty years of church unity across Doncaster.

A Network of The Jubilee Trust

Built on Relationships, Rooted in Prayer

One Heart One Voice was founded on 23rd September 2004, when Ian & Alyson Mayer gathered Doncaster church leaders for a Leaders Day. Inspired by Romans 15 v5–7, the vision was to reach beyond the core Doncaster Ministers Prayer Fellowship and engage with Church leaders across the denominational spectrum.

The network grew and became the heartbeat of unity across Doncaster for twenty years — through City Celebrations, City Prayer, City Hope, Movement Day Doncaster and beyond — until passing the baton in 2024 to Passion for Doncaster.

What began with a small group gathering for prayer became a tapestry of networks, projects, celebrations and partnerships, each one a chapter in the bigger story of unity across our city.

Watch

Why is Church Unity So Important?

“I love the mathematical definition of unity, ‘a quantity assuming the value of one’. There is a sense here of defining ‘quantity’ in the singular, rather than in the plural. Imagine the church across a locality choosing to be identified in the singular rather than the plural? Every denomination, every stream and flavour saying, we choose to be known as one. What would such a church look like? Are we brave enough to walk a path like this? Is it even a choice?”

— Ian Mayer

Our Journey

Twenty Years of Unity

From the birth of One Heart One Voice in 2004, through the era of City Celebrations and Movement Day, on to the passing of the baton to Passion for Doncaster in 2024 — a timeline of the people, events and partnerships that shaped the journey.

  1. September 2004

    One Heart One Voice is Born

    Prayer for Unity

    Ian & Alyson produce a declaration of unity for Doncaster:

    We declare that Doncaster will be known as a city where the church is seen as one; a city known for its love, compassion and unity; a place where the love of God is outpoured through the church, the community and the marketplace. We pray for Godly leaders who will seek righteousness, peace and joy, to rise up within each area of our Borough; we declare that every soul in our Borough shall have the opportunity to hear the message of Jesus, and that His eternal message of hope will reign over our Borough.

    Movement Day Doncaster

    The Journey Continues

    Ian & Alyson continue to invest in the City of Doncaster through their Business, Civic and Community roles — pursuing the transformational agenda set during Movement Day Doncaster. Through The Jubilee Trust, this includes connecting strategic Christian leaders across Yorkshire, developing transformational community projects, working with civic leadership on community assets and societal agendas, and growing the wider Church, Commercial, Civic and Community connections that make city transformation possible.

10 Lessons From Our Story

What We’ve Learned About Unity

Church unity within cities develops through a combination of spiritual, organisational and relational factors. Here are ten strategies and principles we’ve learned contribute to building unity that lasts.

01

Prayer and Spiritual Alignment

Unity often begins with prayer. Churches coming together in regular prayer gatherings, interceding for their city and seeking God’s guidance, fosters a shared spiritual alignment and a sense of common purpose.

02

Leadership Collaboration

Key leaders from different churches and denominations play a crucial role. Citywide pastor networks and forums provide opportunities for leaders to build relationships, share resources, and work together on common goals.

03

Shared Vision and Values

Establishing a shared vision and core values creates common ground for churches to unite around — often focused on serving the community, spreading the Gospel and addressing social needs.

04

Collaborative Projects

Joint worship services, evangelistic campaigns, community outreach and humanitarian projects facilitate collaboration and build trust — tangible opportunities for churches to demonstrate unity in action.

05

Bridge-Building Organisations

Non-profits, parachurch ministries and citywide alliances dedicated to promoting unity serve as catalysts for collaboration — providing resources, facilitating communication and coordinating joint initiatives.

06

Cultural Sensitivity and Diversity

Recognising and celebrating cultural and denominational diversity within the city is essential. Embracing diversity and learning from one another’s traditions enriches the collective experience of unity.

07

Conflict Resolution & Reconciliation

Addressing conflicts and promoting reconciliation is crucial for sustaining long-term unity — establishing processes for conflict resolution, fostering open dialogue and practising forgiveness.

08

Intentional Relationship-Building

Building relationships among church members and leaders through intentional gatherings, small groups and social events helps break down barriers and foster trust and camaraderie.

09

Public Advocacy & Social Engagement

Collaborating on issues of social justice, advocacy and community development is a powerful way for churches to demonstrate their commitment to unity and make a positive impact on society.

10

Continual Evaluation & Adaptation

Unity is a dynamic process that requires ongoing evaluation, adaptation and renewal — regularly assessing efforts, celebrating successes, addressing challenges, and remaining open to new opportunities.

The kingdom of God advances at the speed of relationships, and as leaders our role is to provide contexts for those who are connected with us to grow and flourish in unity with the wider church.

“Love the Lord your God with all your heart and with all your soul and with all your mind … love your neighbour as yourself.”

Matthew 22:37–39
