31. There arises further in this connection a question about angels. For they are happy in the enjoyment of Him whom we long to enjoy; and the more we enjoy Him in this life as through a glass darkly, the more easy do we find it to bear our pilgrimage, and the more eagerly do we long for its termination. But it is not irrational to ask whether in those two commandments is included the love of angels also. For that He who commanded us to love our neighbour made no exception, as far as men are concerned, is shown both by our Lord Himself in the Gospel, and by the Apostle Paul. For when the man to whom our Lord delivered those two commandments, and to whom He said that on these hang all the law and the prophets, asked Him, "And who is my neighbour?" He told him of a certain man who, going down from Jerusalem to Jericho, fell among thieves, and was severely wounded by them, and left naked and half dead. And He showed him that nobody was neighbour to this man except him who took pity upon him and came forward to relieve and care for him. And the man who had asked the question admitted the truth of this when he was himself interrogated in turn. To whom our Lord says, "Go and do thou likewise;" teaching us that he is our neighbour whom it is our duty to help in his need, or whom it would be our duty to help if he were in need. Whence it follows, that he whose duty it would be in turn to help us is our neighbour. For the name "neighbour" is a relative one, and no one can be neighbour except to a neighbour. And, again, who does not see that no exception is made of any one as a person to whom the offices of mercy may be denied when our Lord extends the rule even to our enemies? "Love your enemies, do good to them that hate you."
