to the OP:
we baptize in the nearest clean river/lake - if anyone is 'doing' a baptism, it would be the father of the house or in some cases, just the person immersing themselves...we fellowship with groups of believers, sometimes in homes, sometimes in buildings...sometimes not at all.
I didn't read 12 pages of responses - especially the back and forth between catholics adn protestants...sheesh.
Read the bible, do what it says - let everything else fall to the wind as chaff.
Just my simple response.
Deuteronomy 6:5-7 And thou shalt love YHWH thy Elohim with all thine heart, and with all thy soul, and with all thy might. And these words, which I command thee this day, shall be in thine heart: And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up.
