John Chrysostom
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.
(Hom. lxvi. 2) He illustrates His discourse by an example from nature. A grain of corn produces fruit, after it has died. How much more then must the Son of God? The Gentiles were to be called after the Jews had finally offended; i. e. after His crucifixion. Now then that the Gentiles of their own accord offered their faith, He saw that His crucifixion could not be far off. And to console the sorrow of His disciples, which He foresaw would arise, He tells them that to bear patiently not only His death, but their own too, is the only way to good: He that loveth his life shall lose it.
