I need a portable baptistry

[Esaias]

Sorry, baptizo means to immerse. It does not mean "to wash however you get it done".

Baptism is a fullbody .ikvah and infusion (pouring) was a post apostolic development.

I don't know ANY apostolic who accepts pouring or sprinkling as baptism.

Don't know any baptists who pour or sprinkle either, for that matter.

Baptism is for the remission of sins. That guy getting water poured on his head is not being baptised.

I would say I'm shocked but pretty much nothing shocks me nowadays.
