Augustine of Hippo
Catena Aurea · Johannesevangelium 16
And in that day ye shall ask me nothing. Verily, verily, I say unto you, Whatsoever ye shall ask the Father in my name, he will give it you. Hitherto have ye asked nothing in my name: ask, and ye shall receive, that your joy may be full. These things have I spoken unto you in proverbs: but the time cometh, when I shall no more speak unto you in proverbs, but I shall shew you plainly of the Father. At that day ye shall ask in my name: and I say not unto you, that I will pray the Father for you: For the Father himself loveth you, because ye have loved me, and have believed that I came out from God. I came forth from the Father, and am come into the world: again, I leave the world, and go to the Father.
(Tr. cii) He came forth from the Father, because He is of the Father; He came into the world, because He shewed Himself in the body to the world. He left the world by His departure in the body, and went to the Father by the ascension of His humanity, nor yet in respect of the government of His presence, left the world; just as when He went forth from the Father and came into the world, He did so in such wise as not to leave the Father. But our Lord Jesus Christ, we read, was asked questions, and petitioned after His resurrection: for when about to ascend to Heaven He was asked by His disciples when He would restore the kingdom to Israel; when in Heaven He was asked by Stephen, to receive his spirit. And who would dare to say that as mortal He might be asked, as immortal He might not? I think then that when He says, In that day ye shall ask Me nothing, He refers not to the time of His resurrection, but to that time when we shall see Him as He is: which vision is not of this present life, but of the life everlasting, when we shall ask for nothing, ask no questions, because there will remain nothing to be desired, nothing to be learnt.
