Charles Fox Parham
Parham, a Caucasian-American, had been "a Methodist supply pastor"  in Linwood, Kansas. From the Methodist Church, he received the teaching of entire sanctification as a second work of grace. He also adopted the doctrine of divine healing as a part of the atonement from the Holiness movement. From Fire-Baptized Holiness Church, he accepted the teaching of Holy Ghost baptism as a third experience, but rejected the extreme emotionalism of the Fire-Baptized movement. After 1895, when many persons were leaving the Methodist Episcopal Church," he left also. "   Parham was the first person to single out glossolalia [speaking in tongues] as the evidence of Holy Ghost baptism. He taught that it should be a normal part of Christian worship rather than a by-product of religious enthusiasm.
