[129] St. Jerome places the beginning of St. Peter's twenty-five years' episcopate at Rome in A.D. 42--that is, two years before Herod's attempt to put St. Peter to death. This idea has been worked up into an elaborate story, which will be found duly set forth in great detail in Fleury's _Ecclesiastical History_, Book I., where St. Peter is made Bishop of Rome prior to the death of Herod Agrippa, whence he despatches disciples to found Churches in various towns of Italy, and whence he writes his first Epistle to the Jews of the Dispersion in Asia Minor. A simple statement of this is sufficient refutation for any one who knows the bare text of the Acts. There seems, however, no reason whatsoever to doubt the ancient tradition which fixes the martyrdom of St. Peter at Rome. See on the whole subject the interesting article on St. Peter in Schaff's _Encyclopædia of Theology_, p. 1814. In the _Acta Sanctorum_, published by the Bollandists, April, vol. iii., p. 346, we are told that St. Peter despatched St. Mark to found the Church of Aquileia, which claims the next rank to the Church of Rome among the Italian sees. In fact, the Bishops of Aquileia regarded themselves as of such importance, owing to their apostolic origin, that they headed a separation from the Church of Rome, which lasted from about A.D. 570 to 700. See Robertson's _History of the Church_, ii., p. 306, and the authorities there quoted, on this interesting anticipation of the Reformation in England.
The reproof of St. Peter by St. Paul for his dissimulation was made on a public occasion before the whole Church. It must have caused considerable excitement and discussion, and raised much human feeling in Antioch. Barnabas too, the chosen friend and companion of St. Paul, was involved in the matter, and must have felt himself condemned in the strong language addressed to St. Peter. This may have caused for a time a certain amount of estrangement between the various parties. A close study of the Acts of the Apostles dispels at once the notion men would fain cherish, that the apostles and the early Christians lived just like angels without any trace of human passion or discord. The apostles had their differences and misunderstandings very like our own. Hot tempers and subsequent coolnesses arose, and produced evil results between men entrusted with the very highest offices, and paved the way, as quarrels always do, for fresh disturbances at some future time. So it was at Antioch, where the public reproof of St. Peter by St. Paul involved St. Barnabas, and may have left traces upon the gentle soul of the Son of Consolation which were not wholly eradicated by the time that a new source of trouble arose.
The ministry of St. Paul at Antioch was prolonged for some time after the Jerusalem Synod, and then the Holy Ghost again impelled him to return and visit all the Churches which he had founded in Cyprus and Asia Minor. He recognised the necessity for supervision, support, and guidance as far as the new converts were concerned. The seed might be from heaven and the work might be God's own, but still human effort must take its share and do its duty, or else the work may fail and the good seed never attain perfection. St. Paul therefore proposed to Barnabas a second joint mission, intending to visit "the brethren in every city wherein they had proclaimed the word of the Lord." Barnabas desired to take with them his kinsman Mark, but Paul, remembering his weakness and defection on their previous journey, would have nothing to say to the young man. Then there arose a sharp contention between them, or, as the original expression is, there arose a paroxysm between the apostles, so that the loving Christian workers and friends of bygone years, "men who had hazarded their lives for the name of our Lord Jesus Christ," separated the one from the other, and worked from henceforth in widely different localities.
