So, if only the eunuch had said, "There is some water, what prevents me from being water baptized", that would make it okay? A bit redundant don't you think? "Oh, there's some Snickers bars, what prevents me from eating one"? Oops, shouldn't it say "Oh, there's some Snickers bars, what prevents me from eating a Snickers bar?"
heretics in the 16th century introduced nonbiblical language such as “water baptism” and “spirit baptism”
Peter spoke of “baptism”
Paul spoke of “baptism”
Jesus spoke of “baptism”
Christians have believed ONE BAPTISM for 2,000 years.
heretics, not withstanding.
