Dā'mi-an-ist, n.

n. (Eccl. Hist.) A follower of Damianes, patriarch of Alexandria in the sixth century, who made a distinction between the divine essence and the persons of the Father, Son, and Holy Ghost. In other words, they denied that each person by himself and in nature was God, but maintained that the three persons had a common divinity, by an undivided participation of which each one was God.
