John Chrysostom
Catena Aurea · Johannesevangelium 17
I pray for them: I pray not for the world, but for them which thou hast given me; for they are thine. And all mine are thine, and thine are mine; and I am glorified in them. And now I am no more in the world, but these are in the world, and I come to thee. Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are. While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled. And now come I to thee; and these things I speak in the world, that they might have my joy fulfilled in themselves.
(Hom. lxxxi) He was the only one indeed who perished then, but there were many after. None of them is lost, i. e. as far as I am concerned; as He says above more clearly; I will in no wise cast out. But when they cast themselves out, I will not draw them to Myself by dint of compulsion. It follows: And now I come to Thee. But some one might ask, Canst Thou not keep them? I can. Then why sayest Thou this? That they may have My joy fulfilled in them, i. e. that they may not be alarmed in their as yet imperfect state.
