So he acted infallibly when he determined the canon of Scripture?
If yes, then you believe in "Sola Luthera."
You know, I was going to say in my previous post that Catholics and Protestants can at least agree upon the fact that Luther was fallible. But I guess I was wrong.
In all fairness, STA, most mainline Protestants would agree with Catholics on that, but you have to understand that there are fringe, peripheral nutjobs who are "sola scriptura" wannabe church of one, who make up their own nutjob "theology" as they go along.
Not so long ago, one of these individuals posted that St. Paul spent three years in "heaven with the Lord", where he was taught everything, before returning to earth to preach the gospel of the resurrected Christ!
One way you can tell who these nutjubs are if by simply asking them what Protestant denomination they belong to. They will ignore such questions—persistently—because they know if they pick a mainline denomination its members will publicly disown them and expose them as the trolls that they are.
