In November 2009, the Roman Catholic website Called to Communion posted an article titled Solo Scriptura, Sola Scriptura, and the Question of Interpretive Authority, critiquing one of the claims of my book The Shape of Sola Scriptura (Canon Press, 2001). The article is attributed to Bryan Cross and Dr. Neal Judisch. According to their website, Cross is a graduate of Covenant Theological Seminary (M.Div.) and currently a Ph.D. student at Saint Louis University. He converted to Roman Catholicism in 2006. Judisch is a professor of philosophy at the University of Oklahoma and a 2008 convert to Roman Catholicism. Like the other regular authors at Called to Communion, Cross and Judisch come from a Reformed background and are relatively recent converts to Roman Catholicism.
The main point of their article is stated in the opening paragraphs
Read it all here: Thoughts of Francis Turretin: Solo Scriptura, Sola Scriptura, and Apostolic Succession: A Response to Bryan Cross and Neal Judisch (by Keith Mathison) [Guest Post].
I like the bit questioning why “oneness” has to be a present fulfillment but “holy” can be an eschatological reality.
According to how Mathison defines Sola Scriptura, I don’t think he’s being faithful to the Reformed standards, nor do other people. A year before Mathison’s reply, even people like Turretin Fan agree (see comment #238 by TurretinFan):
