Now which Baptism is the ONE BAPTISM that Paul spoke of in Ephesians? He said there was ONE BAPTISM in this dispensation, not two or several..
Since Paul was commissioned by the RISEN CHRIST as the Apostle to the Gentiles and the Gospel of the GRACE of God was given to him to preach for the formation of the Body if Christ, it would seem paramount that anyone interested in being part of that Body would know about the ONE BAPTISM he proclaimed
Christ knows.
