Catena Aurea on John 12:44–50: Augustine of Hippo

i. e. I judge him not now. He does not say, I judge him not at the last day, for that would be contrary to the sentence above, The Father hath committed all judgment unto the Son. (5:22) And the reason follows, why He does not judge now; For I came not to judge the world, but to save the world. Now is the time of mercy, afterward will be the time of judgment.
