At long last, we have the first pope to not be recognized as a saint. It was a bummer, too, because Liberius is the only pope in the first 49 popes to not bear that title. Liberius is recognized, however, as a saint by the Eastern Orthodox Church. 

He reigned as pope for 14 years through some tumultuous times, when Arianism was still in full force, and when the emperor (Constantius) was particularly favorable to this unorthodox view. Liberius was exiled for a time, but was eventually returned to Rome and given a hero’s welcome by the faithful. He had a basilica erected during his tenure, one we now know as St. Mary Major in Rome. Liberius died on September 24, 366.

Pope Liberius is typically known as being one of three popes used by non-Catholics as an example of why papal infallibility isn’t a real thing. The rumor was that Liberius signed a heretical creed and thereby proclaimed error, which would’ve made the infallibility of the pope a sham. 

Here’s the real story: Pope Liberius was the crown jewel of Constantius’ effort to force Arianism on Christianity; having the Roman pontiff bend to his will would have been his greatest victory. History shows that the emperor threw every kind of method of coercion in order to have him renounce the true faith. For TWO YEARS Liberius was put under this duress, but the pope remained unmoved. 

The major beef -- where we get the bad rumor from -- that Liberius was out of line is due to both St. Athanasius (alive at the time) and St. Jerome (writing years later) asserting that Liberius had signed the heretical creed and renounced the true faith. The problem with this is not only that Athanasius, in exile at the time, may not have had all the correct details, and that Jerome was using forged letters as sources, but that Liberius would have been coerced into signing, which would make it not an act of free will. And so, infallibility is still intact. Your move, critics. 

Fun fact: Liberius was another pope who had to deal with a rival to his throne. Felix, an archdeacon and an Arian (again, believed Christ was just a man), wanted to play “finders keepers” to the Chair of Peter when Liberius was exiled to Thrace. The clergy in Rome did Liberius a solid, though, and vowed to accept no other bishop until his return or his death.

In 361, construction of the Monastery of St. Anthony began in Egypt’s Eastern Desert.
