Book of Mormon, Mosiah 16:7 (emphasis added) …

“And if Christ had not risen from the dead, or have broken the bands of death that the grave should have no victory, and that death should have no sting, there could have been no resurrection.”

This verse is said to have been written around 148 B.C., yet it is presented in the past tense.

See Isaiah 25:8 (AKJV) and 1 Corinthians 15:54-55 (AKJV); ref – E.D. Howe, Mormonism Unvailed (Painesville, OH: Howe, 1834), 64.
