St. Thomas thus detects a primary source of presumption in seeking genuinely good things, like human happiness on earth, as if we did not need divine grace to attain them; and in the hope that we can obtain God’s pardon and mercy without our confessing and repenting of sin.

Each practical moral virtue has two opposed vices, a “too much” and a “too little” (e.g., cowardice and foolhardiness, or insensitivity and self-indulgence).

And so too here, with the sacraments. On the one hand, superstition ascribes supernatural powers to the natural things themselves, not as instruments; and on the other hand, in the typically Muslim Ash’arite theology, God does everything Himself and acts not by using natural things as active instruments but only as accidental occasions.
