So? The vast majority of Catholics merely invoke the clause "that truth which G-d, for the sake of our salvation, wished to see confided to the Sacred Scriptures" and then say obviously when the Bible says the world was created in six days it doesn't actually mean that the world was created in six days; or that when the Bible says that Adam lived 930 years it doesn't really mean that he actually lived for 930 years; or that the story of Noah's Ark was not "confided to Sacred Scripture" to give us any factual information about Noah or the Ark. Oh no, these are inspired allegories and fables and it is only the non-factual "theological truth" behind them that is infallible. Furthermore, G-d used pagan mythologies to teach this truth.
Do you deny that this is the attitude of most Catholics and practically all the clergy?
Did you even read what I said prior to my quotation of the Catechism?
Protestants seem to make faith a work which must be done properly, so that the Fides quae creditur must be correct if salvation is to be assured. I could be wrong about this, but that's what it looks like to me. But the RC Church places a lot of confidence in the mercy of Christ and while it tries to be clear about what orthodoxy is, it doesn't necessarily get the vapors if Mrs. MacIllicuddy has some pretty weird ideas about things. We trust God to straighten things out and are happy to entrust Mrs. MacIllicuddy to His forgiving and gentle care.
Yes, I know you don't believe me. But the point is that the belief of people in the pew and even of some clergy is not necessarily identical with the teaching of the Church.
How do you come to know what the attitude of "practically all the clergy" is? I know only a few priests. You know practically all of them around the world?
