That is news to me. On this thread alone, I am sure I can find more than once a spin on James 2:17-26 that would revolve on exactly that idea, that works follow proper faith. If it now looks to you like a caricature on Protestant exegesis, maybe you should revise your basic theology.
It is very good, on the othor hand, that Protestant pastors preach what the Bible teaches. One day they will all be Catholic then.
Or perhaps one day you will understand that they already WERE members of the "universal" body of Christ. Hopefully, you will be, too.
