Augustine of Hippo
Catena Aurea · Johannesevangelium 7
And many of the people believed on him, and said, When Christ cometh, will he do more miracles than these which this man hath done? The Pharisees heard that the people murmured such things concerning him; and the Pharisees and the chief priests sent officers to take him. Then said Jesus unto them, Yet a little while am I with you, and then I go unto him that sent me. Ye shall seek me, and shall not find me: and where I am, thither ye cannot come. Then said the Jews among themselves, Whither will he go, that we shall not find him? will he go unto the dispersed among the Gentiles, and teach the Gentiles? What manner of saying is this that he said, Ye shall seek me, and shall not find me: and where I am, thither ye cannot come?
(Tract. xxxi. 9) He does not say, Where I shall be, but Where I am. For Christ was always there in that place whither He was about to return: He returned in such a way, as that He did not forsake us. Visibly and according to the flesh, He was upon earth; according to His invisible majesty, He was in heaven and earth. Nor again is it, Ye will not be able, but, Ye are not able to come: for they were not such at the time, as to be able. That this is not meant to drive men to despair, is shewn by His saying the very same thing to His disciples; Whither I go, ye cannot come; and by His explanation last of all to Peter, Whither I go, ye cannot follow Me now, but ye shall follow Me afterwards.
