Article XIXOf the Cause of Sin
p. 43 Of the Cause of Sin, they teach, that although God doth create and preserve nature, yet the cause of sin is the will of the wicked, that is, of the devil and ungodly men; which will, unaided of God, turns itself from God, as Christ says [John 8:44]: “When he speaketh a lie, he speaketh of his own.”
