Matthew 7:2

Those being trained toward piety put the bridle of good thought on the tongue, allowing it to speak only what does no harm. Teaching us this, one of the wise said: “Child, if you have a word of understanding, answer; if not, let a hand be on your mouth.” For “death and life are in the hand of the tongue” — that is, in its power — “and those who master it will eat its fruits.”

And since mastering the tongue is not very easy, the psalmist also teaches us from above: “Set a guard, Lord, on my mouth.” So let us not speak against one another or condemn the brothers. The one steered by understanding does not look at others’ sins, but gazing at his own evils drops a good tear over them, that he may receive forgiveness from God.

It is impossible for humans, weak as we are, not to fall into a few absurdities at all. Not falling at all belongs by nature to God alone. We who are in sins must not delight in others’ evils, but take thought how we ourselves may get outside what is base.
