The Primacy of the Church. Christianity is often called the religion of the Book: this is because it is based on things that happened in history. Jesus did not leave behind Him, so far as we know, a single written word. We hear of His writing only once, and then it was on the dust of the floor of the temple (John 8.6). What He did leave was a community—the eleven faithful Apostles, the ministering women, His mother and brothers—about 120 persons in all (Acts 1.15), who met daily for worship because they loved Jesus and believed that God had raised Him from among the dead. When they had to fill the place of the traitor Judas, Peter said: ‘Of the men therefore which have companied with us all the time that the Lord Jesus went in and out among us, beginning from the baptism of John, unto the day that he was received up from us, of these must one become a witness with us of his resurrection’ (Acts 1.2 if). And Matthias was chosen, with all possible care. Six weeks later the company was wonderfully strengthened and increased by the outpouring of the Spirit, and the Church began to spread from Jerusalem to ‘all Judaea and Samaria, and unto the uttermost part of the earth’ (Acts 1.8).
