Galatians 1:6 I marvel that you are so soon removed from him that called you into the grace of Christ unto another gospel 

‘Removed from him that called you into the grace of Christ’ Twenty things wrong with the Galatians: Being so soon removed from Christ (1:6). Permitting false teachers to pervert the gospel (1:7; 5:8-12). They were bewitched from obedience to the gospel of Christ (3:1; 5:7). They were crucifying Christ anew (3:1). Attributing their gospel blessings to the law of Moses (3:2). Beginning in the Spirit and seeking perfection in the flesh (3:3). Suffering for the gospel in vain by losing gospel benefits (3:4). Going back to the law of works to be justified (3:10-12; 5:4). Turning back to the weak and beggarly elements of the world (4:9). Desiring to be in bondage (4:9, 21). Going back to the observance of sabbaths and other festivals of the law (4:9-10). They considered Paul an enemy for telling them the truth (4:16). Were zealous for wrong things (4:17-18). Backslidden and in need of rebirth again (4:19). Were back in bondage to the law (5:1). Being convinced of circumcision (5:2). Were fallen from grace (1:6; 5:4). Using liberty as an occasion for the flesh to sin (5:13). Biting and devouring one another (5:15, 5:26). Seeking to escape the persecution of the cross of Christ (6:12).

‘Another gospel’ – the other gospel was the law which: Cannot justify (2:16; 3:11; 5:4); brings only the curse (3:10); is not of faith (3:12); cannot give an inheritance (3:18); was added only to make sin sinful (3:19; Rom. 3:19-20; 7:13; 1Jn. 3:4); was given only until Christ came (3:19, 23-25; Heb. 7:28; 9:9-10; Luke 16:16); could not give life (3:21); could not give righteousness (3:21); was a schoolmaster to lead to Christ (3:24-26; Matt. 11:11; Luke 16:16); is not in force for Christians (3:19-25); makes servants, not sons (4:1-3); brings bondage (4:9, 24; 5:1); was a religion of days, etc. (4:10); could not give the new birth (4:28-30); was cast out (4:21-31); demanded circumcision (5:2-3); if observed, cancels grace (5:4).
