All Commentaries on Galatians 1:5 Go To Galatians 1
John Chrysostom
AD 407
This too is new and unusual, for we never find the word, Amen placed at the beginning of an Epistle, but a good way on; here, however he has it in his beginning, to show that what he had already said contained a sufficient charge against the Galatians, and that his argument was complete, for a manifest offense does not require an elaborate crimination. Having spoken of the Cross, and Resurrection, of redemption from sin and security for the future, of the purpose of the Father, and the will of the Son, of grace and peace and His whole gift, he concludes with an ascription of praise.
Another reason for it is the exceeding astonishment into which he was thrown by the magnitude of the gift, the superabundance of the grace, the consideration who we were, and what God had wrought, and that at once and in a single moment of time. Unable to express this in words, he breaks out into a doxology, sending up for the whole world an eulogium, not indeed worthy of the subject, but such as was possible to him. Hence too he proceeds to use more vehement language; as if greatly kindled by a sense of the Divine benefits, for having said, To whom be the glory for ever and ever, Amen, he commences with a more severe reproof.
