To make use of what is needful for self-support is not the sin of gluttony; but if a man do anything inordinate out of the desire for such support, it can pertain to the sin of gluttony.

Context

“And Christ resisted these temptations by quoting the authority of the Law, not by enforcing His power, "so as to give more honor to His human nature and a greater punishment to His adversary, since the foe of the human race was vanquished, not as by God, but as by man"; as Pope Leo says (Serm. 1, De Quadrag. 3) . Reply Obj. 1: To make use of what is needful for self-support is not the sin of gluttony; but if a man do anything inordinate out of the desire for such support, it can pertain to the sin of gluttony. Now it is inordinate for a man who has human assistance at his command to seek to obtain food miraculously for mere bodily support. Hence the Lord miraculously provided the children of Israel with manna in the desert, where there was no means of obtaining food otherwise.” source
