I'm constantly surprised by the innovative, experimental groups of people who gather together from different faith backgrounds. Here's one thats been around for 13 years and could be a way forward for some communities in the UK. Perhaps they already exist and I haven't discovered them yet.
"Companions on the Journey" describes a group of Roman Catholics and persons from other faith traditions who have gathered as an independent non-hierarchical Eucharistic community since May 1997. Each individual’s faith is derived from his/her experiences of God, immanent and transcendent, and is illuminated by the teachings of Christ and the wisdom of other spiritual traditions.
