Because their entire agenda is built on baptismal regeneration — the belief that the act of baptism itself causes salvation. That’s why they constantly shift the order, putting obedience and water before faith and grace. Scripture never teaches that. The moment we make baptism the instrument of salvation instead of the response to it, we’ve replaced the gospel of grace with a system of works.
Grace and Peace
IMO this kind of purposeful misrepresentation is part of the learned and practiced Calvinist methodology of creating fraudulent framings to give its ideas the appearance of truth. No one says baptism causes salvation and no one says obedience and water precede faith and grace. These are straw men that you set up and then knock down in an attempt to try to win the argument.
