You didn't cite any theological concepts.  You just mentioned encyclicals from the past.

And I doubt that you even know the historical [and political] backgrounds that prompted these letters to be written.  In the Vatican today, theologians, curia and popes just brush past the crap that was in Mirari Vos.  Same thing with the Syllabus of Errors.  Just about everything condemned in these 'rags' the Vatican now has and uses [and can't do without].  

Truth is a large deer, nobody, no age can eat it all at one time.
