I like this post. Especially #6
6) So, who is more likely to be closer to the original teaching of the Apostles? The Catholic Church, following the beliefs and practices of the early Christians who first received the teaching of the Apostles directly, or those who, 1500 years or more after the fact, reinterpreted the writings of the Apostles to mean things that Christians had never believed before and rule out as corruption and heresy those things that Christians had always believed/practiced from the very beginning?
Use a different argument.
What happens when you use this one is you are bypassing the legitimacy of the claim of Apostolic Succession and tying it all to a claim of fact that cannot be verified due to passage of time.
Eventually I suppose someone will come up with a really neat response and we will all flock to Orthodoxy or something.
