Acts 15:5 - Ellicott's Commentary On The Whole Bible

Certain of the sect of the Pharisees which believed. — This is the first distinct mention of the conversion of any of the Pharisaic party, but there had been a drift in that direction going on for some time, beginning during our Lord’s ministry (John 12:42), and showing itself in the moderate counsels of Gamaliel (Acts 5:38-39). The position which they occupied was that of accepting Jesus as a teacher sent from God, proved by the Resurrection to be the Christ, and as such the Head of a kingdom which was to present to mankind a restored and glorified Judaism, the Law kept in its completeness, the Temple ritual still maintained, Gentiles admitted only on their confessing their inferiority and accepting the sign of incorporation with the superior race. It appears, from Galatians 2:1, that here, as in so many later controversies, the general issue was debated on an individual case. Was Titus — a Greek, i.e., a Gentile, whom St. Paul had brought up with him — to be circumcised, or not? Was he to be admitted to communion with the Church, or treated as a heathen? Here, probably, there was no official rank as in the case of Cornelius, no previous transition stage in passing through the synagogue as a proselyte of the gate. He was a Gentile pure and simple, and as such his case was a crucial one. Circumcision, however, did not stand alone. It carried with it every jot and tittle of the Law, the Sabbaths and the feasts, the distinction between clean and unclean meats. It may be noted that the position which Titus occupied in this controversy gave him a special fitness for the work afterwards assigned to him, of contending against the party of the circumcision, with their “Jewish fables” and false standards of purity (Titus 1:10; Titus 1:14-15).
