How did Origen describe the union of the divine Logos and Jesus Christ?

According to the theologian Origen, the incarnation involved the divine Logos—the second hypostasis of the Trinity—uniting himself with a preexistent soul that had never fallen away from God.1

Origen described the intensity of this union between the Logos and Christ’s soul as being comparable to the union of a body and soul, or to white-hot iron permeated by fire. Through this profound connection, the Logos became incarnate in a body derived from the Virgin Mary. While Christ’s soul possessed free will, the intensity of its union with the Logos was so complete that it eliminated any inclination for change. Furthermore, Origen taught that the Logos united himself to both the soul and the body of Jesus, a reality he believed was evidenced during the Transfiguration.1
