 Origen was the first Christian to speak of three “hypostases” in the Trinity and to use the term homoousios (though only by analogy) of the relation between the second of these hypostases and the first. The Father, or first person, is nevertheless the only one who is autotheos, God in the fullest sense, whereas the Son is his dunamis or power and the Spirit a dependent being, operative only in the elect. All three are eternal and incorporeal, the Son being known as Wisdom in relation to the Father and Logos (reason, word) in relation to the world. In this capacity he is the shepherd of rational beings the logikoi, who, according to his later critics, were said in his lost writings to have been in origin incorporeal beings coeval with the world if not eternal, and currently imprisoned in material bodies only because of a cooling in their love. It is not so easy to demonstrate from his extant works that he held the material world in such contempt, though he certainly holds it to be created out of nothing and suspects that the concept of matter is philosophically redundant. Souls, in his view, are sent down into bodies (perhaps never more than once, though again some critics impute to him a doctrine of transmigration or chronic falling away from bliss). The soul remains indefeasibly free in its choices, and the misuse of this freedom is the cause of its captivity to the devil.
