A Church that is right all along has no need of dialog; it only has a need to teach.  Rejection of that teaching is not necessarily evil, and, if you were made to feel that way, is a shame on him who did so (and, here, I take you at your word that it was not merely a pricking of conscience).  None of us, individually, know the mind of God, but the mind of the Church, in irreformable matters, is certainly the mind of God.  We can argue and disagree all we want on matters of theological opinion (Limbo, the instant of the souls departure from the body, why God created peonies) but an argument against the dogmatic deserves and receives no dialog; those are stare decisis in the most decisis of manner.
There are many things that I might change, given the chance.  It is a chance that I don't have and, upon consideration, don't want.
Thank you, Matt, for your reply.
