The Apology of the Augsburg Confession
Article XIX The Cause of Sin
[77] The adversaries accept Article XIX. In it we confess that only God and He alone has created all nature and preserves all things that exist. Yet the cause of sin is the will of the devil and people turning away from God, according to the saying of Christ about the devil, “When he lies, he speaks out of his own character” (John 8:44).
