Believer’s baptism and infant baptism are two independent and complementary traditions that have been practiced since the early church. In fact, many of the earliest churches practiced both. Infant baptism has several meanings, depending upon one’s tradition, but it is usually a covenantal ceremony decided upon by the parents that positions the child into the church family.
Believer’s baptism is different in that it is an intentional proclamation by the follower of Jesus. Believer’s baptism in no way negates or disrespects one’s baptism as an infant.
