Galatians 1:2 - Coke's Commentary on the Holy Bible

And all the brethren, &c.— Not all believers in general, but those who accomplished St. Paul in his travels, and assisted him in preaching the Gospel. Such were Timothy, Clement, and others, who are denominated fellow-labourers in other places. See Philippians 4:3. 1 Thessalonians 3:2. When St. Paul writes to the Christians of any particular city, he generally uses the singular number, the church: but the province of Galatia contained several cities and churches. This was an evident seal of his apostleship, since in Galatia, a small province of the Lesser Asia, he had, after no long stay among them, planted several distinct churches. It is remarkable, that the Apostle does not make use of any of the endearing epithets, as the beloved, the saints, the brethren, &c.; and there might be good reason for it: the Galatians had suffered his verymission to be called in question, without attempting any vindication of it, and had given countenance to doctrines which were subversive of the very foundation of Christianity.
