📖 Biblical Definition
Justification is the forensic (legal) act of God whereby He declares a sinner righteous on the basis of Christ's atoning work received through faith — not because the sinner has become righteous, but because the righteousness of Christ has been credited (imputed) to His account. It is an instantaneous, complete, unrepeatable divine verdict: "Not guilty; righteous." Romans 3–5 is the magna carta of justification: sinners are "justified by His grace as a gift, through the redemption that is in Christ Jesus" (3:24). Justification must be distinguished from sanctification: justification is the declaration of righteousness; sanctification is the progressive growth in righteousness. The Reformation rediscovery of this distinction — sola fide, by faith alone — was the article on which the church stands or falls.

Roman Catholic theology blurs the distinction between justification and sanctification, treating justification as an ongoing process involving merit and sacramental infusion — making it partly God's act and partly human achievement. Modern evangelical culture often collapses justification into "God accepting me as I am" without grasping the legal exchange: Christ's righteousness credited, our guilt removed. Conversely, progressive Christianity reduces justification to social liberation from systemic oppression, evacuating the term of its personal, forensic, and redemptive content. The Reformers saw clearly: if justification is corrupted, the entire gospel collapses.
