I was provoked Erv, by Bugs,

I was picking nits.    In my opinion, you should refer to the man holding Papal office by his taken papal name, and historically the same man is referred to by his taken name when discussing his papacy.  When you refer to the time preceding his papacy, you use his given name.  Popes are not born, they are elected.  It would be inappropriate (and confusing) if your teachers had called you Professor Taylor. But your students ought to address you using your honorific title.

A good editor catches little things.  And big ones too.  The big thing is --- you have Pius IX completely out of context portraying his statements as attacks on reason when they are in written in defense of reason.  Pius is defending Aquinas' understanding of unfallen reason and actually taking your part in the argument against what he and Aquinas called 'invincible ignorance.'  People who bullheadedly refuse to look at evidence are 'invincibly ignorant' according to Pius IX.
