Throughout most of Christian history, to be “born again” was understood as spiritual regeneration via the sacrament of baptism. This is still the understanding in Roman Catholicism and Eastern Orthodoxy. However, beginning with the Reformation, being born again is predominantly understood by Protestants, Episcopalians and Lutherans are two notable exceptions to this understanding, to be an experience of conversion symbolized by water baptism, rooted in commitment to one’s personal faith in Jesus Christ for salvation. A metaphorical rebirth occurs when a person accepts Jesus as the Messiah and receives the Holy Spirit. Within evangelical Protestantism, the term “born again” has come to be associated with a new concept, an experience of conversion, defined as mental assent to the acceptance of Jesus Christ as their personal Saviour.
