Catena Aurea · Lukasevangelium 1
To perform the mercy promised to our forefathers, and to remember his holy covenant; The oath which he sware to our father Abraham, That he would grant unto us.
(Hom. in Ps. 29. et in Ps. 14. App. op.) But let no one, hearing that the Lord had sworn to Abraham, be tempted to swear. For as when the wrath of God is spoken of, it does not signify passion but punishment; so neither dos God swear as man, but His word is in very truth expressed to us in place of an oath, confirming by an unchangeable sentence what He promised.
