Agreed. But both the baptism of Jesus and our baptism are physical not metaphysical. Hence the one baptism spoken of by Paul in Romans 6:3 and Eph. 4:5-6. The one baptism spoken of in the great commission is a physical water baptism not metaphysical. No one can attest to a metaphysical baptism such as the Baptism of the Holy Spirit mentioned in the New Testament.
Who hath also sealed us, and given the earnest of the Spirit in our hearts. 2 Corinthians 1:22
In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, Ephesians 1:13
