When, therefore, did "Cephas come down to Antioch?" The Galatians evidently knew. The Judaizers had given their account of the matter, to Paul's disadvantage. Perhaps he had referred to it himself on his last visit to Galatia, when we know he spoke explicitly and strongly against the Circumcisionists (ch. i. 9). Just before his arrival in Galatia on this occasion he had "spent some time" at Antioch (Acts xviii. 22, 23), in the interval between the second and third missionary journeys. Luke simply mentions the fact, without giving any details. This is the likeliest opportunity for the meeting of the two Apostles in the Gentile capital. M. Sabatier,[51] in the following sentences, appears to us to put the course of events in its true light:--"Evidently the Apostle had quitted Jerusalem and undertaken his second missionary journey full of satisfaction at the victory he had gained, and free from anxiety for the future. The decisive moment of the crisis therefore necessarily falls between the Thessalonian and Galatian Epistles. What had happened in the meantime? _The violent discussion with Peter at Antioch_ (Gal. ii. 11-21), and all that this account reveals to us,--the arrival of the emissaries from James in the pagan-Christian circle, the counter-mission organized by the Judaizers to rectify the work of Paul. A new situation suddenly presents itself to the eyes of the Apostle on his return from his second missionary journey. He is compelled to throw himself into the struggle, and in doing so to formulate in all its rigour his principle of the abolishment of the Law."
