Before the emergence of the holiness movement in the mid-19th century and Pentecostalism in the early 20th century, most denominations believed that Christians received the baptism with the Holy Spirit either upon conversion and regeneration or through rites of Christian initiation. Since the growth and spread of Pentecostal and charismatic churches, however, the belief that the baptism with the Holy Spirit is an experience distinct from regeneration has come into increasing prominence.
