Actually, to be biblical baptism must be by immersion. The very word "baptize" in the Greek is baptizo (βαπτίζω) means "dip, immerse" (Gingrich Lexicon and any other lexicon, including one I have in Japanese). Likewise, the noun "baptism" (baptisma, βάπτισμα) means "immersion."
When sprinkling or pouring is done pretending to be baptism, the beautiful symbolic meaning of being buried and raised with Christ (Romans 6:3-4) is lost.
I see Romans 6:3-4 as referring to the baptism of the Holy Ghost rather than water baptism.
Romans 6:3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
Sharing a post from another thread in my search for water baptism by sprinkling.
Ezekiel 36:25 Then will I sprinkle clean water upon you, and ye shall be clean: from all your filthiness, and from all your idols, will I cleanse you.
26 A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
27 And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.
There are a lot of verses regarding the sprinkling of the blood that cleanses as well but I will not bother with that aspect.
The Book of Numbers also list a few references of the actual sprinkling of water for several cleansing purposes.
Numbers 8:7 &
Numbers 19:13 &
Numbers 19:18-21
Nothing about sprinkling of water as a form of water baptism in the New Testament yet.
The one below is not to be taken as such an example.
Hebrews 10:21 And having an high priest over the house of God;
22 Let us draw near with a true heart in full assurance of faith,
having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.
23 Let us hold fast the profession of our faith without wavering; (for he is faithful that promised
I am sure
Hebrews 10:21-23 has nothing to do with water baptism, but the baptism with the Holy Ghost.
Titus 3:4 But after that the kindness and love of God our Saviour toward man appeared,
5 Not by works of righteousness which we have done, but according to his mercy he saved us,
by the washing of regeneration, and renewing of the Holy Ghost;
6
Which he shed on us abundantly through Jesus Christ our Saviour;
7
That being justified by his grace, we should be made heirs according to the hope of eternal life.
Anyway, so far, I find no New Testament example of water baptism by sprinkling but then again, it is the baptism with the Holy Ghost that counts for salvation rather than any specific form of water baptism to be insisted upon for discipleship.
