Rebaptism

Rebaptism in Christianity is the baptism of a person who has previously been baptized, usually in association with a denomination that does not recognize the validity of the previous baptism.^[1][2] When a denomination rebaptizes members of another denomination, it is a sign of significant differences in theology. Churches that practice exclusive believer's baptism, including Baptists and Churches of Christ, rebaptize those who were baptized as infants because they do not consider infant baptism to be valid. However, churches from such denominations deny that they rebaptize because they do not recognize infant baptism as baptism at all.

Rebaptism is generally associated with:

• Anabaptism, from Greek ἀνα- (re-) and βαπτίζω (I baptize)
• Denominations that require believer's baptism, such as the Baptist churches
• Mormonism
• Oneness Pentecostal churches
