This is not the Christian teaching. There is no such thing as a Christian community unless it is made up of individuals who are already Christians through the work of Christ. One can talk about Christian community until one is green, but there will be no Christian community except on the basis of a personal relationship with the personal God through Christ. The Christian community is made up of those whom the Good Shepherd knows by name as His sheep, those who are in relationship with God, who stand in a living way as a branch to the vine, the bride to the Bridegroom, those who have come to the living God through the work ofjesus Christ as He died upon the cross. This is the difference between the sacraments of baptism and the Lord's Supper.
Baptism is once for all.
It represents a man's acceptance of Christ as Savior and then being baptized at that moment with the Holy Spirit. The Lord's Supper is taken constantly because it represents Christians' feeding upon Christ, which should be constant, moment by moment-to use the modern word, existential. These are the ones who should be making up the Christian community. We have looked carefully at the individual as he stands in relationship to God. The community stands in the same place.
