John Chrysostom
Catena Aurea · Lukasevangelium 3
Then said he to the multitude that came forth to be baptized of him, O generation of vipers, who hath warned you to flee from the wrath to come? Bring forth therefore fruits worthy of repentance, and begin not to say within yourselves, We have Abraham to our father: for I say unto you, That God is able of these stones to raise up children unto Abraham. And now also the axe is laid unto the root of the trees: every tree therefore which bringeth not forth good fruit is hewn down, and cast into the fire,
It is elegantly said, that beareth not fruit, and it is added, good. For God created man an animal fond of employment, and constant activity is natural to him, but idleness is unnatural. For idleness is hurtful to every member of the body, but much more to the soul. For the soul being by nature in constant motion does not admit of being slothful. But as idleness is an evil, so also is an unworthy activity. But having before spoken of repentance, he now declares that the axe lies near, not indeed actually cutting, but only striking terror.
