Christian Formation

What is sanctification?

Sanctification is the work of God’s grace by which people are made holy and conformed to Christ. Christian traditions agree that holiness is grounded in Christ and the Spirit, but differ over how sanctification relates to justification, sacraments, human cooperation, perfection, and final glory.

The question

Where the disagreement lies

The word can describe a decisive setting apart, a lifelong transformation, and the final completion of holiness. The readings below share biblical language while giving different weight to growth in obedience, participation in divine life, the means of grace, and the possibility of deeper or entire holiness in this life.

Summary

On this reading, God accepts sinners by grace through Christ and then renews them over time. Sanctification is real but incomplete in this life: believers fight sin, practice obedience, receive the means of grace, and grow in love without turning their progress into the ground of acceptance.

What this contributes

It gives assurance and transformation their proper relationship. Holiness is not an alternative way to earn salvation, but the necessary fruit of union with Christ and the Spirit’s continuing work.

Question to keep in view

Critics ask whether a strong distinction between justification and sanctification can make transformation seem secondary or leave too little room for decisive experiences of holiness.
