Deuteronomy 32:20

“Moreover, you were commanded to abstain from certain kinds of food, in order that you might keep God before your eyes while you ate and drank, seeing that you were prone and very ready to depart from His knowledge, as Moses also affirms: ‘The people ate and drank, and rose up to play.’ And again: ‘Jacob ate, and was satisfied, and waxed fat; and he who was beloved kicked: he waxed fat, he grew thick, he was enlarged, and he forsook God who had made him.’ For it was told you by Moses in the book of Genesis, that God granted to Noah, being a just man, to eat of every animal, but not of flesh with the blood, which is dead .” And as he was ready to say, “as the green herbs,” I anticipated him: “Why do you not receive this statement, ‘as the green herbs,’ in the sense in which it was given by God, to wit, that just as God has granted the herbs for sustenance to man, even so has He given the …

Then I said again, “Would you suppose, sirs, that we could ever have understood these matters in the Scriptures, if we had not received grace to discern by the will of Him whose pleasure it was? in order that the saying of Moses might come to pass, ‘They provoked me with strange [gods], they provoked me to anger with their abominations. They sacrificed to demons whom they knew not; new gods that came newly up, whom their fathers knew not. Thou hast forsaken God that begat thee, and forgotten God that brought thee up.

The Lord, accordingly, does not wish to look on evil things; for He is good. But on His looking away, evil arises spontaneously through human unbelief. “Behold, therefore,” says Paul, “the goodness and severity of God: on them that fell, severity; but upon thee, goodness, if thou continue in His goodness,” that is, in faith in Christ.

What kind of persons does He bid should be invited to a dinner or a supper? Precisely such as he had pointed out by Isaiah: “Deal thy bread to the hungry man; and the beggars, even such as have no home, bring in to thine house,” because, no doubt, they are “unable to recompense” your act of humanity. Now, since Christ forbids the recompense to be expected now, but promises it “at the resurrection,” this is the very plan of the Creator, who dislikes those who love gifts and follow after reward. Consider also to which deity is better suited the parable of him who issued invitations: “A certain man made a great supper, and bade many.” The preparation for the supper is no doubt a figure of the abundant provision of eternal life. …
