John Chrysostom : "That being enriched in every thing to all liberality, which worketh through us thanksgiving to God." Not that ye may consume it upon things not fitting, but upon such as bring much thanksgiving to God. For God made us to have the disposal of great things, and reserving to Himself that which is less yielded to us that which is greater. For corporeal nourishment is at His sole disposal, but mental He permitted to us; for we have it at our own disposal whether the crops we have to show be luxuriant. For no need is here of rains and of variety of seasons, but of the will only, and they run up to heaven itself. And largeness in giving is what he here calls liberality. "Which worketh through us thanksgiving to God." For neither is that which is done almsgiving merely, but also the ground of much thanksgiving: yea rather, not of thanksgiving only, but of many other things besides. And these as he goes on he mentions, that by showing it to be the cause of many good works, he may make them thereby the forwarder. — Homily 20 on 2 Corinthians Philoxenus of Mabbug : And again Paul himself prayed for those who give that the fruits of their righteousness might be increased, and that they might distribute gifts to the needy with simplicity, "May that God Who giveth seed to the sowers, and bread for food, multiply your seed, and increase the fruits of your righteousness; that ye may be enriched in everything in all simplicity, which perfecteth by our hand thanksgiving to God." And behold here also in simplicity Paul prayeth for his disciples that they may be enriched, and that therefrom, he saith, thanksgiving towards God may increase and wax strong. — 13 Ascetic Discourses, Discourse 4 -- On Faith: First Discourse on Simplicity
