Christians in almost every tradition have given a special place in the life of the church to the two signs of God's grace (or sacraments) of baptism and Holy Communion. Both rest on the clear instructions of Jesus to his disciples and the practice of the earliest Christians recorded in the New Testament. Both remain very important for fresh expressions of church.
Some fresh expressions of church begin in a sacramental tradition and are formed around Holy Communion.
However, many other fresh expressions of church take time to reach the point in their journey where they develop an appropriate way of celebrating Holy Communion together and where they begin to baptize new believers. The important thing is to discern the right time and the right way to develop these essential marks of what it means to be the church and grow in grace.
