What's the Grounding Objection?

One of the biggest s that moved me towards catholicism and during my conversion experience, was not so much teaching on authority, it was the teaching on salvation. I would love if someone like james white, who critiques molanism with something like the grounding objection, then says, we don't really need tho ground. For me, just reading it, w i took it the catholic view make sense. This is process that. Now, of course, when you have protestantism and catholicism, it's like there's a wide gamut of views ind protestantism about how we're saved,. ye, his very walls.
