Chapter 18: Salvation Through Union with ChristAt-One-Ment and the Meaning of “Cleaving” to the Lord

Understanding Mormonism, 2026 Annotated Edition

Updated

In brief

How does Christ’s death actually save us? Seaich argues that images such as ransom, scapegoat, and penal substitution are “similitudes” taken from the Law of Moses, not the essential explanation. John’s Gospel goes deeper. Christ laid down his life and took it up again to show his power over death and to “draw all men” to himself. Through baptism and the Holy Ghost, believers “cleave” (Greek kollaō, Hebrew dabhaq) to him and become one Spirit with him. That is the literal sense of “at-one-ment.”
