Moroni 8:18, Psalm 90:2, and the Latter-day Saint Understanding of Deity (cf. (cf. Email exchange with a Confused Calvinist on LDS Theology and Christology; Latter-day Saints have Chosen the True, Biblical Jesus;The Christological Necessity of Universal Pre-Existence)
Spiros Zodhiates on עוֹלָם (cf. David Bentley Hart on Greek and Hebrew Concepts of Eternity and David Bentley Hart on Matthew 25:46 and the meaning of αἰώνιος)
