thanks brianroy for the link.
Baptism emerged as a key Christian ritual. Baptized Christians who had prepared themselves to follow Christ, after an extensive period of study, prayer and fasting, shared in his death and resurrection on Easter, the Sunday after Passover. They, too, would someday join him in Paradise.
this i will address first. 1st : baptism didn't emerge. that is a wrong interpretation of the command. it was nstituted at the beginning not only by John the Baptist but by Christ's act of baptism by John. then in the great commission we see these words:
Matthew 28:19
Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost
this is not an emerging ritual but a direct command on what believers are to do as they save souls.
the rest of the article would take more time to research and compare but i think he misunderstands the function of the gospels and inserts a modern view into scriptures which need to be looked at from the ancient view.
what i have found over the years is that many people forget the many uses and meanings that come with the english language and that they tend to look at passages with a limited modernidea instead of the full english meanings.
this is becoming a problem in communication as people get insulted whenthey do not realize the speaker or writer was using a different aspect of the english language than they used when reading or listening.
i have seen this take place on many occasions especially on chat room forums.
I don't see the relevance of where 'baptism' came from but I would like to state that it did not come from where you are stating, immersion,k dates back to the giving of the laws at Mt Sinai, ritual cleansing took place for men, woman, the sick, animals, utensils and many other things. This have always been an outward practice of unclean vs clean in since the time of Moses. This is misunderstood by many Christians, just as they believe that the immersion of Jesus was the same as all the others that had been immersed under John. They were making 'teshuvah', a return to G-d and his ways, Jesus had no need for that because this was the spotless lamb of G-d, just as John announced. He was immersed as per the priestly induction at age 30 into the priesthood.
