“Since the time when the Roman pontiffs reserved to themselves definite decision in causes of canonization and beatification, the title of confessor (pontiff, non-pontiff, doctor) belongs only to those men who have distinguished themselves by heroic virtue which God has approved by miracles, and who have been solemnly adjudged this title by the Church and proposed by her to the faithful as objects of their veneration.”

Thanks for the remark about the Salesian and Ottonian dynasties. And despite what you noted, people still go around quoting Voltaire about how the Holy Roman Empire was neither holy nor Roman.

This Ottonian and Salesian line of kings were very strong Catholics. They saw themselves as the King Davids of the New Israel. As such they took it upon themselves to right the wrongs going on in the Church. This is during the same period as the Hildebrand reforms trying to clean up simony, the abuse of investiture, and a whole bunch of clerical immorality. Even the non-celibate kings of this line were very good Catholics (up until Henry IV).

Recommend reading the Investiture Crisis by I think Una Renate Blumenthal (not sure if this is the right author?)

Spiritual Marriage by Dyan Elliott, which is about the apparently common medieval practice of married couples living in either unconsummated marriages or later taking vows of chastity.

In a more recent example, a couple from this past century, Maria and Luigi Quattrocchi — canonized by Pope John Paul the Fair in 2001 — lived a chaste marriage for the last 26 years of their lives.
