Wesley's second blessing, kept when the Methodists let it go.
The largest denomination in the Wesleyan-holiness tradition, assembled in 1908 out of a dozen independent holiness groups that had left or been pushed out of Methodism for insisting on entire sanctification as a distinct experience after conversion. It ordained women from the start, dropped the word Pentecostal from its name in 1919 to avoid being confused with the tongues movement, and is now a body of some 2.7 million in 165 world areas, most of them outside the United States.
Why it is filed this way
The Nazarenes are Wesleyan-holiness rather than Pentecostal, and the distinction is one they have defended since 1919, when they removed Pentecostal from their name. Both movements teach a second work of grace after conversion; the Pentecostals attach speaking in tongues to it as the evidence, and the Nazarenes do not.
