Catena Aurea · Johannesevangelium 12
And there were certain Greeks among them that came up to worship at the feast. The same came therefore to Philip, which was of Bethsaida of Galilee, and desired him, saying, Sir, we would see Jesus. Philip cometh and telleth Andrew: and again Andrew and Philip tell Jesus. And Jesus answered them, saying, The hour is come, that the Son of man should be glorified. Verily, verily, I say unto you, Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit. He that loveth his life shall lose it, and he that hateth his life in this world shall keep it unto life eternal. If any man serve me, let him follow me; and where I am, there shall also my servant be: if any man serve me, him will my Father honour. Philip cometh and telleth Andrew.
(Tr. li. 10) But think not for an instant, that by hating thy soul, is meant that thou mayest kill thyself. For wicked and perverse men have sometimes so mistaken it, and have burnt and strangled themselves, thrown themselves from precipices, and in other ways put an end to themselves. This did not Christ teach; nay, when the devil tempted Him to cast Himself down, He said, Get thee hence, Satanb. But when no other choice is given thee; when the persecutor threatens death, and thou must either disobey God’s law, or depart out of this life, then hate thy life in this world, that thou mayest keep it unto life eternal.
