Baptism is being “born again”
[B]y the name of Jesus Christ of Nazareth, whom you [Jews] crucified, whom God raised from the dead, by Him this man stands here before you whole. This is the ‘stone which was rejected by you builders [Jews], which has become the chief cornerstone.’ Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved.Acts 4:10-12.
The name of Jesus, not any Church, and believing and receiving Him, is the only way anyone is saved.
