This quarrel appears most extraordinary on the part of St. Paul. Having been at first a persecutor, he might have been expected to have acted with moderation; especially as he had gone to Jerusalem to sacrifice in the temple, had circumcised his disciple Timothy, and strictly complied with the Jewish rites, for which very compliance he now reproached Cephas. St. Jerome imagines that this quarrel between Paul and Cephas was a pretended one. He says, in his first homily (vol. iii.) that they acted like two advocates, who had worked themselves up to an appearance of great zeal and exasperation against each other, to gain credit with their respective clients. He says that Peter--Cephas--being appointed to preach to the Jews, and Paul to the Gentiles, they assumed the appearance of quarrelling--Paul to gain the Gentiles, and Peter to gain the Jews. But St. Augustine is by no means of the same opinion. "I grieve," says he, in his epistle to Jerome, "that so great a man should be the patron of a lie."--(_patronum mendacii_). This dispute between St. Jerome and St. Augustine ought not to diminish our veneration for them, and still less for St. Paul and St. Peter. As to what remains, if Peter was destined for the Jews, who were, after their conversion, likely to Judaize, and Paul for strangers, it appears probable that Peter never went to Rome. The Acts of the Apostles makes no mention of Peter's journey to Italy. However that may be, it was about the sixtieth year of our era that Christians began to separate from the Jewish communion; and it was this which drew upon them so many quarrels and persecutions from the various synagogues of Rome, Greece, Egypt, and Asia. They were accused of impiety and atheism by their Jewish brethren, who excommunicated them in their synagogues three times every Sabbath-day. But in the midst of their persecutions God always supported them. By degrees many churches were formed, and the separation between Jews and Christians was complete before the close of the first century. This separation was unknown to the Roman government. Neither the senate nor the emperors of Rome interested themselves in those quarrels of a small flock of mankind, which God had hitherto guided in obscurity, and which he exalted by insensible gradations. Christianity became established in Greece and at Alexandria. The Christians had there to contend with a new set of Jews, who, in consequence of intercourse with the Greeks, had become philosophers. This was the sect of _gnosis_, or gnostics. Among them were some of the new converts to Christianity. All these sects, at that time, enjoyed complete liberty to dogmatize, discourse, and write, whenever the Jewish courtiers, settled at Rome and Alexandria, did not bring any charge against them before the magistrates. But, under Domitian, Christianity began to give some umbrage to the government.
