The Holiness movement is a Christian movement that emerged chiefly within 19th-century Methodism, and to a lesser extent influenced other traditions, such as Quakerism, Anabaptism, and Restorationism. Churches aligned with the holiness movement teach that the life of a born again Christian should be free of sin. The movement is historically distinguished by its emphasis on the doctrine of a second work of grace, which is called entire sanctification or Christian perfection. The word Holiness refers specifically to this belief in entire sanctification as an instantaneous, definite second work of grace, in which original sin is cleansed, the heart is made perfect in love, and the believer is empowered to serve God. For the Holiness movement, "the term 'perfection' signifies completeness of Christian character; its freedom from all sin, and possession of all the graces of the Spirit, complete in kind." A number of Christian denominations, parachurch organizations, and movements emphasize those Holiness beliefs as central doctrine.
In addition to the regular holding of church services in the morning and evening of the Lord's Day, and usually having a midweek Wednesday church service, within parts of denominations or entire denominations aligned with the holiness movement, camp meetings and tent revivals are organized throughout the year—especially in the summertime. These are aimed at preaching the New Birth (first work of grace) and entire sanctification (second work of grace), along with calling backsliders to repentance. Churches in the holiness tradition emphasize a sober lifestyle, especially with regard to clean speech, modesty, and teetotalism.
