Review status: initial-release
Christians agree that faith should change a life, but they describe that change differently. Some speak of sanctification as God’s work of making believers holy over a lifetime; others as theosis — participation in the divine life; others as entire sanctification, a decisive work of grace. All six traditions insist that holiness matters, while differing on how it happens and how far it goes in this life.

Christians agree that following Jesus should make you a different person — but they describe that transformation differently. Catholics teach that God’s grace doesn’t just declare you righteous, it actually makes you holy from the inside out, and this growth continues through the sacraments, prayer, and works of love. The Orthodox call it "theosis" — becoming by grace partakers of God’s own life, a journey that never ends. Lutherans say good works are the necessary fruit of faith, not the root of salvation — faith must produce love or it’s dead. The Reformed teach that sanctification is real but imperfect in this life: a lifelong war between the Spirit and remaining sin. Baptists describe sanctification as the Holy Spirit’s ongoing work of setting believers apart and maturing them, continuing all their lives. Methodists, following John Wesley, teach that God’s grace can go further — "entire sanctification" or "Christian perfection": a heart so filled with love that deliberate sin is left behind, even in this life.
