Luke 3:8

It is one thing to bring forth fruits of penance, and another to bring forth worthy fruits. We should know that the man who has committed nothing unlawful, may have a right to use the lawful things of the world, and can perform works of piety, without forsaking innocent enjoyments, unless he pleases. But, if he has fallen into great crimes, let him abstain from what is lawful, as much as he has transgressed, by yielding to guilt. Nor is equal penance required of him who has sinned little, and of him who has fallen into many crimes. And let those, whose consciences convict them, labour to lay up a treasure of good works, proportioned to the injury they have done themselves by their sins. (St. Gregory, hom. xx. in Evang.) --- It is not sufficient for penitents to forsake their sins, they must also bring forth worthy fruits, according to that of the psalmist, decline from evil, and do good. (Psalm xxxvi.) As it is not enough to extract the dart; and external application is also necessary. He says not fruit, but fruits, to shew the abundance of good works we ought to perform. (St. John Chrysostom, hom. x. on S. Matt.) --- He does not mean to say that they did not descend from Abraham, but that their descending from Abraham would avail them nothing, unless they kept up the succession of his virtues. (St. John Chrysostom, hom. xi. and xii. on S. Matt.) --- What can those be thought but stones, who have given themselves to the adoration of stones; to which, says the psalmist, they are assimilated, who place their trust in them? By this the Baptist prophesies, that faith shall be infused into the stony hearts of the Gentiles, who by faith shall become the children of Abraham. (St. Ambrose) --- Consider, says St. John Chrysostom, how St. John draws them from boasting of their pedigree, and trusting to their descent from Abraham, to place their hope of salvation in the practice of penance and a holy life. (hom. xi.) --- A lesson this for Catholics, not to expect to find mercy at the last day, for being members of the true religion, unless they live up to the maxims which it prescribes. If I should have all faith, so that I could move mountains, and have not charity, I am nothing. (1 Corinthians xiii. 2.)
