That's a pretty damning link you posted.
I have no patience or time with Catholic "apologists" who spend their time trying to trash or otherwise discredit other Catholic apologists who are making a good-faith effort to be orthodox, as I believe both Mr. Shoeman and Mr. Shea are). If you think the other guy is in error, take it up with him privately. Don't write articles or post websites to trash someone else's reputation.
And the ultimate decision on a Catholic's orthodoxy or lack thereof belongs to the person's pastor, his ordinary, the SCDF, or the Pope. Not to Internet bloggers or magazine publishers.
I killed my subscription to New Oxford Review after their vicious little hit piece on Scott Hahn, and this is the reason why.
Trying to say here that IMO both Mr. Shoeman and Mr. Shea are making a good-faith effort to be orthodox, and don't deserve the treatment they received.
