Theurge

He acknowledged Christ to be a most excellent man, the friend of God, the admirable theurge; he denied, however, that Jesus designed to abolish entirely the worship of demons...

The father was known simply as a philosopher, the son as a theurge...

In other words, the theurge makes himself known to and recognized by the gods, like the mysta in his initiation, by means of 'symbols', signs or passwords (synthemata).

In this process the human mediator's own role was significantly increased from that of middleman theurge to god-imitating demiurge, not only bringing the images to life inside himself in the form of an “inner sculpting,” but...giving them external form as spirits as well.
