Augustine of Hippo
Catena Aurea · Johannesevangelium 13
Little children, yet a little while I am with you. Ye shall seek me: and as I said unto the Jews, Whither I go, ye cannot come; so now I say to you. A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another.
After He had said, And shall straightway glorify Him, that they might not think that God was going to glorify Him in such a way, as that He would no longer have any converse with them on earth, He says, Little children, yet a little while I am with you: as if He said, I shall indeed straightway be glorified by My resurrection, but I shall not straightway ascend to heaven. For we read in the Acts of the Apostles, that He was with them forty days after His resurrection. These forty days are what He means by, A little while I am with you.
