Now the things which I write unto you, behold, before God, I lie not.
All Commentaries on Galatians 1:20 Go To Galatians 1
Augustine of Hippo
AD 430
He certainly swears, and what oath could be more sacred? But an oath is not against the commandment when the “evil cause” is not in the swearer but in the incredulity of him to whom he is forced to swear. For we understand from this that what the Lord meant in prohibiting oaths was that everyone, so far as in him it lies, should not swear the oaths that many do, having the oath on their lips as though it were something lofty and elegant.
