Catena Aurea on John 16:29–33: John Chrysostom

But since His answer met what was in their minds, they add, Now we are sure that Thou knowest all things. See how imperfect they yet were, after so many and great things now at last to say, Now we are sure &c. saying it too as if they were conferring a favour. And needest not that any man should ask thee; i. e. Thou knowest what offends us, before we tell Thee, and Thou hast relieved us by saying that the Father loveth us.
