John Calvin on Romans 2:22

22. Thou who abhorrest idols, etc. He fitly compares sacrilege to idolatry, as it is a thing of the same kind; for sacrilege is simply a profanation of the Divine Majesty, a sin not unknown to heathen poets. On this account Ovid (Metamor. 3,) calls Lycurgus sacrilegious for despising the rites of Bacchus; and in his Fasti he calls those sacrilegious hands which violated the majesty of Venus. But as the Gentiles ascribed the majesty of their gods to idols, they only thought it a sacrilege when any one plundered what was dedicated to their temples, in which, as they believed, the whole of religion centered. So at this day, where superstition reigns, and not the word of God, they acknowledge no other kind of sacrilege than the stealing of what belongs to churches, as there is no God but in idols, no religion but in pomp and magnificence. “Sacrilege,” mentioned here, is by some taken literally as meaning the robbing of God as to the sacrifices he required, and the profanation of sacred rites; “many examples of which,” says Turrettin, “are recorded by the Prophets, and also by Josephus, both before and during the last war.” But some extend its meaning to acts of hypocrisy and ungodliness, by which God’s honor was profaned, and the glory due to him was denied. The highest sacrilege, no doubt, is to deprive God of that sincere service and obedience which he justly requires. “They caused,” says Pareus, “the name and honor of God to be in various ways blasphemed by their wicked hypocrisy; and hence they were justly said by the Apostle to be guilty of sacrilege.” He then adds, “we must notice, that idolatry is not opposed to sacrilege, but mentioned as a thing closely allied to it. Indeed all idolatry is sacrilegious. How then can the Monks, Priests, and Jesuits clear themselves from the charge of sacrilege? for they not only do not detest idolatry, being in this respect much worse than these hypocrites, but also greedily seek, like them, sacred offerings, and under the pretense of sanctity devour widows’ houses, pillage the coffers of kings, and, what is most heinous, sacrilegiously rob God of his due worship and honor and transfer them to saints.” Yet the world is so blind as not to see the real character of such men! — Ed.

Now we are here warned, first, not to flatter ourselves and to despise others, when we have performed only some portions of the law, — and, secondly, not to glory in having outward idolatry removed, while we care not to drive away and to eradicate the impiety that lieth hid in our hearts.
