Daniel!!! What a piece of work. It’s book quality! I just scanned it, now need to read it. THANK YOU!!
It certainly is a piece of something. It doesn't prove anything other than the Catholic point that Scripture is NOT self interpreting. It proves that even if one accepts Sola Scriptura, one needs an equally infallible teaching authority in order to not be in error on significant issues of dogma and doctrine. After I clean up the errors in the "what Catholics can disagree on" lists I will probably use this in my RCIA and apologetics classes.
It also proves that Protestants, by definition, are a pretty disagreeable lot. After you get past the unity of not accepting the authority of the Church or the Apostolic Tradition Protestants don't agree on much else to the point that even calling them an identifiable group is a stretch.
Peace be with you.
