So true, but just what EXTRA stuff that Rome failed to put into the Book is needed to get a person to heaven?
It's not "Extra Stuff that Rome failed to put into the Book" -- that formulation presupposed Sola Scriptura.
It's not "needed to get a person to Heaven" -- it's an extra channel of Grace; an opportunity, not a universal requirement.
Although it might be highly efficacious for some.
