Do not think that you can show your love for Christ by hating those who seem to be His enemies on earth. Suppose they really do hate Him: nevertheless He loves them, and you cannot be united with Him unless you love them too. If you hate the enemies of the Church instead of loving them, you too will run the risk of becoming an enemy of the Church, and of Christ; for He said: “Love your enemies,” and He also said: “He that is not with me is against me.” Therefore if you do not side with Christ by loving those that He loves, you are against Him. But Christ loves all men. Christ died for all men. And Christ said there was no greater love than that a man should lay down his life for his friend.
