The purpose of the NDCU is to develop existing relationships, giving expression to koinonia, and sharing and receiving the gifts which each member church has to offer.

Formed in 2016, the member churches are Anglicans, Roman Catholics, Methodists, Presbyterians, and the Religious Society of Friends (Quakers). A number of ecumenical organisations, and other denominations such as the Salvation Army, are associated as ‘observers’.

A twice-yearly newsletter is produced, the latest is now available.
