Luke 6:43
Douay-Rheims
For there is no good tree that bringeth forth evil fruit; nor an evil tree that bringeth forth good fruit.
Isidore of Pelusium
(lib. iv. ep. 81.) He does not then exclude repentance, but a continuance in evil, which as long as it is evil cannot bring forth good fruit, but being converted to virtue, will yield abundance. But what nature is to the tree, our affections are to us. If then a corrupt tree cannot bring forth good fruit, how shall a corrupt heart?
