The Holiness movement, which arose from Methodism and other evangelical groups in the 1800s, has key beliefs that set it apart from other movements. The movement embraces John Wesley's teachings on "Christian perfection" where the believer is enabled to live a holy life by the baptism of the Holy Spirit. They believe in a second work of grace (entire sanctification) where it is possible to live entirely free from voluntary sin. Holiness groups also practice the moral aspects of God's law in their behavior as well.
