Augustine of Hippo
Catena Aurea · Matthäusevangelium 5
Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy. But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you and persecute you; That ye may be the children of your Father which is in heaven: for He maketh His sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust. For if ye love them which love you, what reward have ye? do not even the Publicans the same? And if ye salute your brethren only, what do ye more than others? do not even the Publicans so? Be ye therefore perfect, even as your Father which is in heaven is perfect.
(ubi sup.) Or we may take it of this visible sun, and of the rain by which the fruits are nourished, as the wicked mourn in the book of Wisdom, The Sun has not risen for us. (Wisd. 5:6.) And of the rain it is said, I will command the clouds that they rain not on it. (Is. 5:6.) But whether it be this or that, it is of the great goodness of God, which is set forth for our imitation. lie says not, ‘the sun,’ but, His sun, that is, the sun which Himself has made, that hence we may be admonished with how great liberality we ought to supply those things that we have not created, but have received as a boon from Him.
