I will get back to you. The citation I have turns out to have come from a book in our Mission library, not one I have in my own collection. I was able in my own library to find reference to some French scholars who have argured for the Orthodox rather than the Latin interpretation of Cyprian: John Meyendorff cites Be'venot's introduction and notes for
De catholicae ecclesiae unitate in ACW 25. (Westminster: Newman, 1957), A. d'Al`es,
La the'ologie de St. Cyprien (Paris: Beauchesne, 1922), and P.-Th. Camelot, "St. Cyprien et la primaute'," Istina 4 (1957) 421-434. I think the specific source which quote's later writings of St. Cyprian was Philip Sherrard's Church, Papacy and Schism. I'll look on my way to my office tomorrow.
Thanks a lot. Don't go out of your way to find it and please take your time. I was stunned that you said St. Cyprian did not defend the "C of P" - I had always read that he had and, after your post, I could not find anything that stated any differently. If there are writings of his that I haven't seen contrary to what I have seen, I would love to read them.
Thanks for helping me out.
