Baptism with the Holy Spirit [SEP] Introduction
In Christian theology, baptism with the Holy Spirit, also called baptism in the Holy Spirit or baptism in the Holy Ghost, has been interpreted by different Christian denominations and traditions in a variety of ways due to differences in the doctrines of salvation and ecclesiology. It is frequently associated with incorporation into the Christian Church, the bestowal of spiritual gifts, and empowerment for Christian ministry. Spirit baptism has been variously defined as part of the sacraments of initiation into the church, as being synonymous with regeneration, as being synonymous with Christian perfection that empowers a person for Christian life and service.
