No. We recommend but do not require baptism for church membership. The purpose of baptism is to publicly announce that we have been identified with Jesus Christ as our Savior. Water baptism has, throughout the ages, been a means of visibly representing a real, yet invisible, change that has taken place. Paul in Romans 6:1-4 describes this invisible change as the Holy Spirit identifying each believer with Christ in both His death and resurrection. We practice baptism by immersion to follow the pattern of Jesus’ baptism, as described in Matthew 3:16 and Mark 1:10. Even though we cannot literally “follow Jesus in baptism” because His baptism was unique, by immersing we can “follow Him in practice.”
