When the RCC - or any other ministry - proclaims dogma that is contrary to what the Bible does contain, then we have standing to discuss and refute. Such is the case with myriad RCC doctrine and dogmas, as have bee listed in this thread by Dr. E.
I have seen precious little discussion and refutation on this thread. More, I have seen ridicule, profanation and slander. What has been posted has been under dispute, so I would say that we disagree... but it is certainly not unbiblical. There is nothing in the doctrines and dogma of the Church which are contrary to Scripture.
