A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
All Commentaries on Matthew 7:18 Go To Matthew 7
George Leo Haydock
AD 1849
A good tree cannot yield bad fruit 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 (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)
