Matthew 7:18

A good tree cannot yield bad fruit, &c. Not but that both good and bad men may change their lives. This, according to the unanimous consent of the Fathers, is only to be understood while they remain such. If a bad tree begin to produce good fruit, it becomes a good tree, &c. (Witham) --- For not those who do one or two good works are just, but those who continue permanently to do good: in the same manner, not those who commit one or two bad actions are wicked, but those who continue in evil. (Menochius)

Non potest Arbor bona, &c. St. Jerome on this place, brings divers examples to shew, that men's natures are not necessarily or unchangeably good or bad. See St. Augustine, lib. ii. de Serm. Domini in Monte. chap. xxiv. p. 232. Non potest esse nix calida, cum enim calida esse cæperit, non jam eam nivem, sed aquam vocamus. See also St. John Chrysostom Greek: om kg, pag. 168. linea 1.
