I should have taken Karl’s advice on the Journey Home, not to engage, but I stuck my foot in it. I got this from an anti-Catholic site www.thebereans.net , on their forum, where one of them quotes this site. :

The task is to determine what constitutes authentic tradition. How can we know which traditions are apostolic and which are merely human? The answer is the same as how we know which scriptures are apostolic and which are merely human—by listening to the magisterium or teaching authority of Christ’s Church. Without the Catholic Church’s teaching authority, we would not know with certainty which purported books of Scripture are authentic. If the Church revealed to us the canon of Scripture, it can also reveal to us the “canon of Tradition” by establishing which traditions have been passed down from the apostles. After all, Christ promised that the gates of hell would not prevail against the Church (Matt. 16:18) and the New Testament itself declares the Church to be “the pillar and foundation of the truth” (1 Tim. 3:15).
Summarizing it: the Bible is inspired because the church of Rome says so, the Church of Rome is correct in recognizing the Bible’s inspiration because the Bible says so. How convenient! >>
I don’t know if having to deal with their arguements (Exactly in the sequence that Karl said it would happen.) and irrationality has fried my brains, but does any of the above reasoning make ANY sense?
