Warlock (1989)

In Boston of 1691, a warlock is sentenced to death, but escapes magically into the future (our present), followed doggedly by the witch hunter. There he is searching for the three parts of the Devil's Bible, trailed by the witch hunter and the woman whose house he landed in. They must stop him, as the book contains the true name of God, which he can use to un-create the world.
