Galatians 1:11

certify--I made known to you as to the Gospel which was preached by me, that it is not after man, that is, not of, by, or from man (Gal 1:1, Gal 1:12). It is not according to man; not influenced by mere human considerations, as it would be, if it were of human origin. brethren--He not till now calls them so.

In this chapter, after the preface or introduction (Gal 1:1-5), the apostle severely reproves these churches for their defection from the faith (Gal 1:6-9), and then proves his own apostleship, which his enemies had brought them to question, I. From his end and design in preaching the gospel (Gal 1:10). II. From his having received it by immediate revelation (Gal 1:11, Gal 1:12). For the proof of which he acquaints them, 1. What his former conversation was (Gal 1:13, Gal 1:14). 2. How he was converted, and called to the apostleship (Gal 1:15, Gal 1:16). 3. How he behaved himself afterwards (Gal 1:16 to the end).

1:11–2:21 The Judaizers who had come to Galatia preaching faith plus circumcision questioned Paul’s apostleship and attempted to discredit his message. Paul defended his apostolic authority, demonstrating from past events that his message was the true Good News. 1:11 the gospel message I preach: Paul’s message was that people are made right with God by grace through faith, not by obeying the law (see 2:16-17; Rom 10:9-13; Eph 2:8-9).
