Gregory the Great
Catena Aurea · Lukasevangelium 3
And the people asked him, saying, What shall we do then? He answereth and saith unto them, He that hath two coats, let him impart to him that hath none; and he that hath meat, let him do likewise. Then came also Publicans to be baptized, and said unto him, Master, what shall we do? And he said unto them, Exact no more than that which is appointed you. And the soldiers likewise demanded of him, saying, And what shall we do? And he said unto them, Do violence to no man, neither accuse any falsely; and be content with your wages.
(ubi sup.) For because it was written in the law, Thou shalt love thy neighbour as thyself, he is proved to love his neighbour less than himself, who does not share with him in his distress, those things which are even necessary to himself. Therefore that precept is given of dividing with one’s neighbour the two coats, since if one is divided no one is clothed. But we must remark in this, of how much value are works of mercy, since of the works worthy of repentance these are enjoined before all others.
