Chapter 17: Justification and SanctificationDeclared Righteous, Made Holy

Understanding Mormonism, 2026 Annotated Edition

Updated

In brief

What is the difference between justification and sanctification? Justification is God’s legal declaration that a forgiven sinner is righteous, “guilty, but pardoned.” It is not a legal fiction, because it comes only to those who have already received the Holy Ghost. Sanctification is the actual cure. The Spirit’s “refiner’s fire” gradually makes the “babe in Christ” holy, helped by the Church and by trials faced faithfully. The process continues beyond the grave. Seaich compares justification to planting a seed, and sanctification to helping it grow to maturity.
