the first mass weakening of faith in God.
Well, thank God for that!
KJV Matthew 7:17-20:
17Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. 18A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. 19Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. 20Wherefore by their fruits ye shall know them.
What have been the fruits of Christianity? Crusades, the Inquisition, witch trials, forced conversions of foreign people and nearly 3 centuries of war over who was praying in the "correct" manner.
No wonder humanity decided to start determining right and wrong for themselves and making a new morality.
