Nice sidebar to the choir, 1

And which true believers were you speaking to? Your fellow RC’s, the Jews, the Muslims, or one of those weird non-scheduled theologies? All True believers to the last one!
I have to admire your commitment, though, but from the assumptions you accept, what choice do you have? Exactly the same as anyone else who was brought up in whatever they ascribe to themselves as the One, True, and Only God ordained way. And of course they say that after thorough thinking and prayer on the mater to the one and only God. The same one two football teams might pray to to have Him on their side!!! The three stages of growth in religious faith apply evenly across the field; only the contents is different, and I would wonder why universals don’t have precedence in your thinking over particulars?
I would observe as well that while you cite third party authority, “creed” and “church,” you appear to neglect that you have left out a yet higher authority: one’s own integrity and intellectual honesty. It would seem at first blush that you deny that people who disagree with your church haven’t done their homework. Maybe they have, but include more or different perspectives than you allow yourself form within the mental structure you impose on yourself as a believer. We won’t even go into the equivocations that come into play when faithers claim that belief = knowledge, even another “kind” of knowledge. Consistency within a story given certain parameters? Yes. Knowledge? Uhhhhhh… No.
And the one thing that people of any faith, (remember, this is about faith, not Catholicism) repeatedly and consistently go around is that faith is almost always a case of “Post hoc ergo propter hoc.” You learned it that way, therefor its true. The story of the ham and the pan all over. There may have been a reason for it once, but the reason is long lost, yet the form remains as an object in itself.
Does this mean that anyone should stop being a Jew or a Catholic or whatever? No, of course not. There is tremendous good to be had from religious practices, as I well know myself, as well as the horrors spawned by those same beliefs. But there needs to be a commensurate honesty about the fact the we are believers, and we choose to be believers, and that that in itself does not make someone who believes differently wrong on the basis of the particulars of your generalized sameness as faithers.
And certainly if we define prayer as lifting the heart and mind to God, the we all could use more of that. But who are you to say that someone you disagree with doesn’t do that under a different name/Name? We only need to look at the origins and diversity of religions and their similarities from as far back as we can see till now to understand that. Even from your position, that can only at worst be ignorance, not culpability regarding belief in your favorite learned way.
It is also good to remember that much of the Bible, including the words of Master Jesus, are exactly congruent with other interpretations than yours of their meaning. So great, believe what you want on the assumptions you make about the genuineness of your system. But do not use its core of benevolence, which I understand to be there, as a weapon of blame or derision against others.
