Satanians
From BiblePortal Wikipedia
Charles Buck Theological Dictionary [1]
A branch of the Messalians, who appeared about the year 390. It is said, among other things that they believed the devil to be extremely powerful, and that it was much wiser to respect and adore than to curse him.
Cyclopedia of Biblical, Theological and Ecclesiastical Literature [2]
a branch of the Messalians, who appeared about A.D. 390. They derived their name from the theory which they are alleged to have held, that the power of Satan over men makes it right for them to pray that he will not exercise it to their harm. This opinion seems to be the same as that on which the worship of the Yezedees (q.v.) is grounded.
