The Methodist Fellowship Groups, formed of congregations of different cultures have announced their intention to strengthen relationships.
The document by Revd Dr Martyn Atkins, General Secretary of the Methodist Conference, stresses the importance of being one family with one mission and encourages genuine integration.
He said, "We are committed to find continuing and healthy ways to harvest the richness brought into our Church by international communities of Methodists.
"Indeed, every part of the life of the Church is made better because of our life together, and there is much that we can learn from each other."
The Conference is setting up a special advisory and support group to share good practice and encourage integration with local churches.
Revd Dr Claire Potter, Deputy Convener of the working group said: "Fellowship groups are a growing area of the Methodist Church in Britain.
"It is important that we not only understand and welcome the variety and diversity of Fellowship Groups, but that we deepen our current relationships, develop mutual partnerships and genuinely integrate with each other.
"Let us celebrate diversity by learning, accepting and growing together, without enforcing assimilation."
