John 18:9

That the saying might be fulfilled, which He spake, 0f them which Thou gavest Me have I lost none, i.e., of the eleven Apostles which Thou gavest Me: for Judas, as the son of perdition, was not given Him absolutely of the Father. But of what loss and death does Christ here speak: of the soul or of the body? Some say one, some another. But I say, both of body and soul. For they would have perished in the body if they had been seized and slain together with Jesus, more especially because Peter had withstood them and had wounded Malchus. They would have also perished in their souls, because they would have denied Christ in their weakness, and from fear of the threats of the Jews, just as Peter denied Him. And so, when killed by the Jews they would have perished both in body and soul. For they would have died in the mortal sin of denial. So Rupertus, Cajetan, Ribera, F. Lucas, Toletus, and others.
