It teaches us humility. As we were from Adam, so he was from the dust of the earth, and that dust from nothing. Our father was Adam, our grandfather dust, our great-grandfather nothing.Exposition Epistle of Jude, 299
Gluttony is a sin so exceedingly contrary to the love of God: it is idolatry. It hath the heart which God should have . . . because that love, that care, that delight, that service and diligence which God should have, is given by the glutton to his belly and to his throat.
