The church is divided into a hundred different camps regarding this extremely controversial subject. Unfortunately, they are all ignorant of the revelation of the mystery given to Paul, and are oblivious to the cause of their confusion.
If you cannot understand Jesus Christ according to the revelation of the mystery, then you will naturally conclude that we are somehow related to Israel and that we are to follow the preaching and teaching of John the Baptist and Jesus while he walked on the earth. What most do not realize is that water baptism did not originate with John the Baptist nor with Jesus. The people of Israel knew exactly what John was doing.
It was not until after Pentecost when God instituted the dispensation of grace that he gave first to Paul. He would then reveal the secret of the meaning behind his death on the cross. This message of the cross was made available to all men without distinction, covenant status, circumcision, or water baptism. Instead of becoming priests and reigning in an earthly kingdom, the body of Christ today is to assume a heavenly position with Christ as our mediator. No one today can become the priestly mediator to Christ through the washings and anointings of the law.
Rather, by his grace, God freely gives those that believe a high calling in Christ Jesus! Once we believe that Christ was the much-needed blood propitiation for our sins, then we are baptized into the Lord himself!
“For by one Spirit are we all baptized into one body…” – 1 Corinthians 12:13
