Since none of the Apostles disputed it, St. Peter had no need to insist upon it. All knew that Christ had said to him, “Thou art Peter, and upon this rock I will build my Church.” Matt. XVI., 18. And again, “I have prayed for thee, that thy faith fail not: and do thou, being once converted, confirm thy brethren.” Lk. XXII., 32. They knew, too, that Christ’s commission to St. Peter to feed both the lambs and the sheep of the flock included themselves. Jn. XXL, 15-17. Implicitly St. Peter claimed his right by being the first to announce the Gospel after Pentecost, by conducting the election of Matthias as an Apostle in place of Judas, by presiding at the Council of Jerusalem, etc. St. Paul wrote to the Galatians L, 18, that he went to Jerusalem to see Peter, and stayed there fifteen days with him. Why to Peter rather than to any other of the Apostles? And why does he add that, having gone to Jerusalem, he also saw James? He does not say that he went to see such Apostles as were at Jerusalem, or that he went to see James, and also happened to see Peter whilst there.
