Questions about the series

A six-volume study by Eugene Seaich (1925–2006) of ancient texts and Latter-day Saint theology, subtitled “Discovering the Roots of the Eternal Gospel in the Ancient Primitive Church.” The 2026 Annotated Edition is revised and edited, with a foreword, by his grandson Eric Hendrickson.

The Hebrew Bible in its oldest recoverable form, the pseudepigrapha, the Nag Hammadi library and the early Christian fathers, read alongside Latter-day Saint theology.

Apostasy, Orthodoxy, and the Eternal Gospel); Volume 2 — The Mormon Concept of Deity (Father, Son, Holy Spirit, and the Divine Council); Volume 3 — Mormon Anthropology (Preexistence, the Heavenly Council, and the Divine Origin of the Soul); Volume 4 — Mormon Soteriology (Grace, Theosis, and the Three Degrees of Glory); Volume 5 — The Temple (Ancient Temple Symbolism, the Jerusalem Temple, and the Modern Temple); Volume 6 — Gnosticism and the Book of Abraham (The Nag Hammadi Texts, the Papyri, and the Facsimiles).
