Neither of those passages say they was immersed. We can presume or assume they were but the wording of the passage does NOT say they were immersed. It is true that
baptizo often means immersion. For example, the Greek version of the
Old Testament tells us that Naaman, at Elisha’s direction, “went down and
dipped himself [the Greek word here is
baptizo] seven times in the Jordan”. But immersion is not the only meaning of
baptizo. Sometimes it just means washing up. Thus Luke 11:38 reports that, when Jesus ate at a Pharisee’s house, “[t]he Pharisee was astonished to see that he did not first wash [
baptizo] before dinner.” According to Mark, the Pharisees “do not eat unless they wash [
nipto] their hands, observing the tradition of the elders; and when they come from the market place, they do not eat unless they
wash themselves [
baptizo]” (Mark 7:3–4a, emphasis added). So
baptizo can mean cleansing or ritual washing as well as immersion. A historical Christian document called The
Didache was written around A.D. 70 and is a
strong witness to the sacramental practice of Christians in the apostolic age. It said that pouring water three times upon the head was acceptable for baptism.
Ancient Christian mosaics also show pouring for baptism. So,
in review, n
either Scripture nor the historical written practice of NT Christians nor the art work of the early Christianity support the immersion ONLY practice that your men have taught you, however immersion is preferable.
Look at those passages again and ask yourself: Can a person go "into" water and "come up out of the water" without being fully immersed by the water? (the answer is yes)
