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.
