"This indeed is an open thread, which is why I took the liberty to ask if anyone opposed to the idea of Catholic priesthood on scriptural grounds could apply the same rigor of scriptural exegesis to the cardinal Protestant error of Sola Fide."

You won't find much exegesis from the protestants. Their specialty is eisigeis. They begin with the fallacies of Calvin's TULIPs and imprint them into all scripture and discussion. The inability to consider an extra-TULIP interpretation of Scripture or tradition borders on psychotic.

They begin with the fallacies of sole fide and sola scriptura. Not all Protestants subscribe to TULIP.
