(Part three of three)  While Cardinal Newman was not infallible, neither was he a heretic after his conversion.  The RCC does not canonize heretics.  The canonization of Cardinal Newman was an implicit recognition that people of different ages understand Christian dogmas in different ways.

Citing Vatican I as a “solemn declaration”, without specificity is unseemly at best.

The Magisterium errs when it fears rather than uses the social sciences.  The RCC does not have a monopoly on what humans discover as newly true, particularly through scientific discovery, such as that of Galileo.
