That said, I stand very firmly grounded in the doctrines of the Reformed faith and it is equally irritating when I see others condemn something they clearly do not have a firm grasp of. Such is the case with some of the comments in the original article and in some of the responses following.
Unfortunately there is much guilt to go around among defenders of both Catholic and Reformed doctrine. There are possibly more posters who are engaged in sincere and inquisitive discource, but these voices often seem overwhelmed by those involved in theology baiting and name calling, much of it based on ignorance ("Calvinism is intellectually lazy", "Catholics believe that Mary is the redeemer", etc.)
Converted protestants often make the best Catholics (Fr. Neuhaus, Cardinal Newman, etc.) I'm not sure that the same would hold true in the other direction since the days of the original reformers.
