John Chrysostom — as excerpted in the Catena Aurea on Luke 11:37-44

“(Hom. 72. in Joan.) Now He says, give alms, not injury. For almsgiving is that which is free from all injury. It makes all things clean, and is more excellent than fasting; which though it be the more painful, the other is the more profitable. It enlightens the soul, enriches it, and makes it good and beautiful, He who resolves to have compassion on the needy, will sooner cease from sin. For as the physician who is in the habit of healing the diseased is easily grieved by the misfortunes of others; so we, if we have devoted ourselves to the relief of others, shall easily despise things present, and be raised up to heaven. The unction of almsgiving then is no slight good, since it is capable of being applied to every wound.”
