聖潔運動
The traditional Holiness movement is distinct from the Pentecostal movement, which believes that the baptism in the Holy Spirit involves supernatural manifestations such as speaking in unknown tongues. Many of the early Pentecostals originated from the Holiness movement, and to this day many "classical Pentecostals" maintain much of Holiness doctrine and many of its devotional practices. Several of its denominations include the word "Holiness" in their names, including the Pentecostal Holiness Church.
