Page "Glossolalia" Paragraph 66

During the 20th century, glossolalia would primarily become associated with Pentecostalism and the later charismatic movement.

The holiness preachers Charles Parham and William Seymour are credited as co-founders of the movement.

It was Parham who formulated the doctrine of " initial evidence ".

After studying the Bible, Parham came to the conclusion that speaking in tongues was the Bible evidence that one had received the baptism with the Holy Spirit.
