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.) Because a coat is more necessary for our use than a cloak, it belongs to the bringing forth of fruits worthy of repentance, that we should divide with our neighbours not only our superfluities but those which are absolutely necessary to us, as our coat, or the meat with which we support our bodies; and hence it follows, And he who has meat, let him do likewise.
