When the people of the Hebrews were bringing back the ark of the Lord to Jerusalem, Uzzah, from the house of Abinadab the Israelite, who had touched the side of the ark without having examined his conscience, was slain. And yet he had drawn near not to take anything from it but to hold it up when it was leaning because of the stumbling of a young ox. So great a concern was there of reverence toward God that God did not accept bold hands even out of help. The Lord also proclaims the same thing, saying, “Everyone who is clean shall eat of the flesh, and whichever soul touches the flesh of the sacrifice of well-being and has his uncleanness upon him, that soul shall be cut off from his people.” Are these things which existed long ago, and now they do not happen in this way? What then? Has God ceased to care for what concerns us? Has he withdrawn beyond the view of the world, and does he look down from heaven upon no one? Is his forbearance really ignorance? God forbid, you will say. Therefore he sees what we do but he waits, indeed, and endures patiently, and he grants an opportunity for repentance and holds out his own Christ to postpone [the end], so that they whom he has redeemed may not readily perish. Understand this well, you sinner: you are observed by God; you can appease him if you want to.
They [the Galatians] had, in fact, only introduced one or two commandments, circumcision and the observance of days, but he [Paul] says that the gospel was subverted, in order to show that a slight adulteration vitiates the whole. For as he who but partially pares away the image on a royal coin renders the whole spurious, so he who swerves ever so little from the pure faith soon proceeds from this to graver errors and becomes entirely corrupted. Where then are those who charge us with being contentious in separating from heretics and say that there is no real difference between us except what arises from our ambition? Let them hear Paul’s assertion, that those who had but slightly innovated, subverted the gospel. … Don’t you know that even under the old covenant, a man who gathered sticks on the sabbath, and transgressed a single commandment, and that not a great one, was punished with death? And that Uzzah, who supported the ark when on the point of being overturned, was struck suddenly dead, because he had intruded upon an office which did not pertain to him? Wherefore if to transgress the sabbath and to touch the falling ark drew down the wrath of God so signally as to deprive the offender of even a momentary respite, shall he who corrupts unutterably awe-inspiring doctrines find excuse and pardon? Assuredly not. A lack of zeal in small matters is the cause of all our calamities; and because slight errors escape fitting correction, great ones creep in. As in the body, a neglect of wounds generates fever, mortification and death; so in the soul, slight evils overlooked open the door to graver ones.
We read in the law that even those who seem to have acted lightly against the sacred commandments have, nevertheless, been punished most severely. This is that we might understand that nothing which pertains to God must be considered lightly, because even what seems to be very little in fault is made great by the injury to God. What did Uzzah, the Levite of God, do against the heavenly command when he tried to steady the tottering ark of the Lord? There was nothing on this point prescribed by the law. Yet, immediately when he steadied the ark, he was struck down. Not that he was insolent in manner or undutiful in mind. Yet he was undutiful in his very act, because he went beyond his orders.
