The close vital connection between the disciples' work and that of their Master is one of the thoughts most prominent in the last great discourse of Christ to his disciples as pictured in the Fourth Gospel, and it is emphasized in what commentators have called the great priestly prayer. The disciples' lives are to be in close union with their Master's as the vine branches with the parent stem, and beneath all their deeds must flow his living spirit. They must be in union with each other as he is one with the Divine Father, so making real to others the continuance of his life. Their whole lives are to be one great act of priesthood realizing itself through fellowship. For without fellowship priesthood cannot be, and Christianity could not exist. The Church is a society in which men are linked to each other and to God through Christ; there is no place in it for the selfishness of isolated individualism, or the centring of thought upon personal salvation alone. Its members belong to each other in belonging to their head. The metaphors used in the apostolic writings to describe the Church are all social; it is a body, a building, a city, a kingdom, in which every part is in relation to others, and only thus can join to make the whole. The more the children of the Church realize this, the more truly will they become a fellowship of friends, and show themselves such in daily life; theirs will be [p.108] no exclusive friendship, but one which overflows to all, in honest sincerity, because they cannot but work for all men's good.
