***is “Romanist” the preferred term now? What ever happened to “Papist”?***
Papist is still applicable. Romanists is a broader term that encompasses all the idolatries such as Papism, Mariology, the Mass, worshipping of Saints, etc.
***The rest of your question, like you tag line is silly***
I’d much rather be silly than blasphemously believe the Word of God only gains effectiveness with approval of man.
You're right. Who'd be dopey enough to believe that?
Who believes that? Can you cite a specific reference, from an authoritative source that echos that statement? If you're referring to the concept of the magesteriem, I would remind you that "who hears you hears Me".
