Matthew 7:2

This rule, which God will infallibly follow, should put a check to the freedom with which we so frequently condemn our neighbour. (Haydock) --- As we behave towards our neighbours, interpreting their actions with charitableness, and excusing their intentions with mildness; or, on the contrary, judging them with severity, and condemning them without pity; so shall we receive our judgment. (Menochius) --- As the pardon of our sins is proportioned to the pardon we afford to others, so also will our judgment be proportioned to the judgment we pass on others. If our neighbour be surprised by sin, we must not reproach or confound him for it, but mildly admonish him. Correct your brother, not as an enemy, taking revenge, but as a physician, administering appropriate remedies, assisting him with prudent counsels, and strengthening him in the love of God. (St. John Chrysostom, hom. xxiii.)
