Cyril of Alexandria
Catena Aurea · Lukasevangelium 12
And I say unto you my friends, Be not afraid of them that kill the body, and after that have no more that they can do. But I will forewarn you whom ye shall fear: Fear him, which after he hath killed hath power to cast into hell; yea, I say unto you, Fear him. Are not five sparrows sold for two farthings, and not one of them is forgotten before God? But even the very hairs of your head are all numbered. Fear not therefore: ye are of more value than many sparrows.
For it is not absolutely to every one that this discourse seems to apply, but to those who love God with their whole heart to whom it belongs to say, Who shall separate us from the love of Christ? (Rom. 8:3.) But they who are not such, are tottering, and ready to fall down. Moreover our Lord says, Greater love hath no man than this, that a man lay down his life for his friends. (John 15:13.) How then is it not most ungrateful to Christ not to repay Him what we receive?
