If Ephesians 4:4-6 is part of the inspired word of God, which one is that 'one' baptism of the Bible, and what are the implications for those not baptized by that baptism? Will they also go to heaven in view of what Jesus says in John 3:3-5? In Romans 6:3-4, we are told we are buried with Jesus through baptism. Does the blood of Jesus also work for people who have not been baptized by this 'one' baptism or are they worshipping and praying in vain?
