Your take on my position is wrong.
I could set up a persuasive argument one way or the other, that’s what I’m paid to do in real life. But – life really is too short to engage in pissing contests with other Christians, atheists, agnostics, non-Christians or or or. I don’t need to convince myself, and especially I don’t need to convince myself at the expense of tearing down someone else.
Neither you nor anyone else is going to talk me out of my faith, I’m probably not going to sway anyone out of theirs. If that ever happens, it will be because I’m not arguing, but being.
Moreover, I am not responsible for what you choose to believe or how you choose to worship.
How do I “know” I’m right? My conscience was formed by being born and raised RC, having formal secular and religious education by one of the Catholic teaching orders and a life time of experience.
