Hippolytus of Rome, The Refutation of All Heresies X.25: The Elchasaites

But certain others, introducing as it were some novel tenet, appropriated parts of their system from all heresies, and procured a strange volume, which bore on the title page the name of one Elchasai. These, in like manner, acknowledge that the principles of the universe were originated by the Deity. They do not, however, confess that there is but one Christ, but that there is one that is superior to the rest, and that He is transfused into many bodies frequently, and was now in Jesus. And, in like manner, these heretics maintain that at one time Christ was begotten of God, and at another time became the Spirit, and at another time was born of a virgin, and at another time not so. And they affirm that likewise this Jesus afterwards was continually being transfused into bodies, and was manifested in many (different bodies) at different times. And they resort to incantations and baptisms in their confession of elements. And they occupy themselves with bustling activity in regard of astrological and mathematical science, and of the arts of sorcery. But also they allege themselves to have powers of prescience.
