The Benedictine Editor suggests that Cyril “is refuting those who said that the Universe was to perish utterly, an opinion which seems to be somehow imputed to Origen by Methodius, or Proclus, in Epiphanius (Hæres. lxiv. 31, 32).”  On Origen’s much controverted opinions concerning the beginning and end of the world, see Huet. Origeniana, II. 4–6: and Bp. Westcott, Dictionary of Christian Biography, “Origen,” pp. 137, 138.
