Christians find their true identity when they are involved in mission, in communicating to others a new way of life, a new interpretation of reality and of God and in committing themselves to the liberation of others. A missionary community is one that understands itself as being both different from and committed to its environment; it exists within its context in a way which is both winsome and challenging.
