What do Latter-day Saints believe?

These answers summarize the arguments in Understanding Mormonism: The Restored Gospel of Christ and Its Biblical Foundations in Latter-day Saint Belief by Eugene Seaich (2026 Annotated Edition). Each answer names the chapter where the full discussion appears.

Do Latter-day Saints believe they are saved by grace?

Yes. Latter-day Saint scripture teaches salvation “only in and through the grace of God” (2 Nephi 10:24). In Seaich’s account, salvation is a cure for the Fall that no human effort can produce. It is received through faith, repentance, baptism and the gift of the Holy Ghost, which he treats as acts of trust in God rather than meritorious works.

Chapters 4–6

If salvation is by grace, why are good works necessary?

Seaich argues that works do not cause salvation but confirm and preserve it. “Faith without works is dead” (James 2:20), and everyone will be judged and rewarded according to their works (Romans 2:6).

Chapters 11, 12, 14

What does “after all we can do” (2 Nephi 25:23) mean?

Seaich reads the verse as defining “all we can do” as believing in Christ and being reconciled to God: faith and repentance, not earning part of salvation before grace makes up the rest.

Chapter 15

What is the difference between salvation and exaltation?

Salvation is rescue from the Fall. Exaltation is the highest reward of the celestial kingdom, receiving God’s fulness and eternal marriage, and it requires temple ordinances.

Chapters 13, 20, 25

What are the three degrees of glory?

The celestial, terrestrial and telestial kingdoms, compared in 1 Corinthians 15:40–42 to the glory of the sun, moon and stars. Seaich traces the idea to Jesus’ “many mansions” (John 14:2) and to early Christian writers such as Papias and Clement of Alexandria.

Chapter 13

Do Latter-day Saints believe in the Trinity?

Not in the sense of the creeds. The Father, Son and Holy Ghost are understood as separate beings who are one in Spirit, glory and purpose. Seaich argues that the doctrine of one substance (homoousios) developed after the New Testament.

Chapter 21

Do Latter-day Saints believe humans can become like God?

Yes. This is called exaltation. Seaich cites early Christians from Irenaeus to Athanasius who taught that God became man so that man could become divine, and stresses that it is always God’s gift, never a human achievement.

Chapter 20

Why do Latter-day Saints baptize for the dead?

Paul mentions the practice in 1 Corinthians 15:29, and Seaich points to early Christian sources such as the Shepherd of Hermas, Tertullian and Epiphanius. It offers a first chance to those who never heard the Gospel and takes effect only if they freely accept it.

Chapter 24

Was the temple endowment copied from Freemasonry?

Seaich argues the reverse: that Freemasonry preserved fragments of ancient temple tradition, which Joseph Smith recognized and restored within a fuller pattern drawn from ancient Israel’s covenant ceremony.

Chapter 25

Did early Christians believe in a premortal life?

Seaich argues they did. He finds the doctrine in the Wisdom of Solomon, Paul, John and 1 Enoch, and notes that it remained part of Christian thought until it was condemned in A.D. 553.

Chapter 23
