I am not a Catholic and do not rely on the Catholic Church either to speak for me, or to do my thinking for me on such matters.
If you and I agree that Jesus Christ is Himself the Supreme Arbiter of Christian doctrine, we know that if He is God and the Creator, Himself, there's nothing man (or the Catholic Church) can do, or say which has merit apart from that.
You just have to get a grip on Who's Creation it is, regardless of what you purport are Creationist "myths." Are you implying that the Catholic believes the scriptures contain "myths." If so then I'll thank God there was a Reformation.
Your own ego obscures what the Creator-God's scriptures have said on the matter of origins. You are welcome to take it up with the Creator-God and His scriptures yourself. You don't need me for that. Read the scriptures. Approach them with a spirit of honesty, humility and a real desire to learn, and you will find, as I and many others have, that you won't need a Pope or an encyclical to interpret them for you or to do your thinking for you either.
Of course, you know how to read Biblical Hebrew and Koine Greek as well as Aramaic.
You don't need any Pope or any other man to translate the Bible for you, and you don't need any concordance, biblical commentary and lexicon to make sense of the Bible.
You are displaying the typical arrogance and ignorance of Catholic bashers.
But again, you are the Supreme Arbiter of Christian Orthodoxy, therefore unless I agree with your sectarian viewpoint, I'm following men and not the Holy Spirit.
