Augustine of Hippo — as excerpted in the Catena Aurea on John 16:16-22

“(Tr. ci. 1) For above, because He did not say, A little while, but simply, I go to the Father, He seemed to speak plainly. But what to them was obscure at the time, but by and by manifested, is manifest to us. For in a little while He suffered, and they did not see Him; and again, in a little while He rose again, and they saw Him. He says, And ye shall see Me no more; for the mortal Christ they saw no more.”
