Augustine of Hippo

(Tr. cv) Not Thou commandest Me, but, Thou gavest Me, implying evidently grace. For what hath human nature, even in the Only-Begotten, what it hath not received? But how had He finished the work which had been given Him to do, when there yet remained His passion to undergo? He says He has finished it, i. e. He knows for certain that He will.
