I don't know that I can point to a specific "part". Rather the overall tone where one can hear the venom dripping off the words is what raised my eyebrows.
Question anything you like, I know I had some serious in-depth questions for my pastor. It just seems to me, a guy going by the name BibChr would either look at things more objectively, or make a more concerted effort to disguise his disdain for the Catholic church.
It seems your biggest problem is the Catholic belief that we are the "one, true Church" of Jesus Christ. If that's the cause of your bitterness, my advice to you is get over it.
