You know, in the early church they would ask you three questions when they baptized you:
Do you forsake the world?
Do you forsake the flesh?
And then, do you forsake the devil and all his works?
And they would turn to the west and spit 3 times. (which is the symbolic direction of the Antichrist while the Son returns from the east )
And they would announce "I renounce forever Satan and all his works." Then they would plunge you into the water -- the declaration: you die with Christ, you rise with Christ.
From a child of satan to a child of God
