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.
