My understanding is that baptizo was a common word for immersion. The context would tell the reader what the object would be immersed into. It could be water or any other element into which something could be immersed.It is my understanding, the Greek term for "baptism" without other qualifications, I understand it to refer to water baptism.
Passages which do not solely use the term meaning immersion without some other type of qualification, I understand can refer to other than water immersion.
It has been my understanding the passages referenced in my OP baptists have disagreed whether or not they refer to water immersion.
In the Bible, therefore, the believer might be symbolically immersed into Christ Jesus by the Holy Spirit. Water, in that context, would not be the element into which the object is immersed.
