So what exactly are we talking about?
Result of search for "911":
907. baptizo bap-tid'-zo from a derivative of 911; to immerse, submerge; to make whelmed (i.e. fully wet); used only (in the New Testament) of ceremonial ablution, especially (technically) of the ordinance of Christian baptism:--Baptist, baptize, wash.
911. bapto bap'-to a primary verb; to whelm, i.e. cover wholly with a fluid; in the New Testament only in a qualified or special sense, i.e. (literally) to moisten (a part of one's person), or (by implication) to stain (as with dye):--dip.1686. embapto em-bap'-to from 1722 and 911; to whelm on, i.e. wet (a part of the person, etc.) by contact with a fluid:--dip.
"Baptize" means "to dip". People casually assume that means in water, but it does not: the dipping can be in anything. Jesus made that distinction in Acts 1:5.
Acts 1:5 King James Version (KJV)
5 For John truly baptized with water; but ye shall be baptized with the Holy Ghost not many days hence.
"But", get it? That word sets one baptism in contrast to another. I have talked to baptizers who could not read that verse as it is printed because their church taught two baptisms, "co-equal and co-necessary". They would not pronounce that word, not even with coaching. They were literally rewriting the bible as they spoke to agree with what they preferred to believe.
People like to mention Peter's visit to the house of Cornelius in Acts chapter 10.
Acts 10:44-48 King James Version (KJV)
44 While Peter yet spake these words, the Holy Ghost fell on all them which heard the word.
45 And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost.
46 For they heard them speak with tongues, and magnify God. Then answered Peter,
47 Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we?
48 And he commanded them to be baptized in the name of the Lord. Then prayed they him to tarry certain days.
It's funny that they never read the rest of the story:
Acts 11:15-17 King James Version (KJV)
15 And as I began to speak, the Holy Ghost fell on them, as on us at the beginning.
16 Then remembered I the word of the Lord, how that he said, John indeed baptized with water; but ye shall be baptized with the Holy Ghost.
17 Forasmuch then as God gave them the like gift as he did unto us, who believed on the Lord Jesus Christ; what was I, that I could withstand God?
So when you discuss baptizing, you need to remember that water baptism is not a Christian concept, regardless of what you have heard from misinformed preachers.
