Origen (185-254 AD)

"Traces of the Holy Spirit who appeared in the form of a dove are still preserved among Christians. They charm†demons away and perform many cures and perceived certain things about the future according to the will of the Logos." (Origen, Against Celsus, Book I, Chap. XLVI, 2, 8. Post-Nicene Library 10 vols. (Grand Rapids: Wm. B. Eerdmans Publishing Co., 1987))
