Acts 2:37-39. That IS, Christian baptism. Full stop! Nothing of water, or of sprinkling or of immersion or whatever. By this baptism SPOKEN, the believers were baptised with the baptism of Jesus Christ. It is baptism with the Word, through the Word, in the Word and Name of Jesus Christ, God the Father, and the Holy Spirit. It is baptism, in one's own language; it is the baptism of having come to the knowlededge, understanding and assimilation of and within God and His Salvation through faith that cometh by hearing.
