Pretty much every Roman Catholic today agrees that Pope Liberius (the 36th Pope) is not a saint. The Church also claims that he is the first pope not to be canonized a saint, yet ancient Church writings say otherwise. Pope Liberius is referred to as "St. Liberius" as shown in Denzinger right after 57e, while praise is further given to him in Denzinger 88 and 93. The Eastern Orthodox Church (i.e. Schismatics) also consider him a saint and celebrate his feast day on August 27.
Since nobody can take away someone's sainthood, does anyone know why is there this major discrepancy? Does anyone know if Pope Liberius was once considered a valid saint in the Roman Catholic Church? If so, do they know when his sainthood was taken away from him? Or is this yet another error in Denzinger? Of course, I'm referring to the 30th edition that is pre-Vatican II because, after all, how can we really trust subsequent editions?
Yet the 30th edition, pre Vatican II Denzinger was partly edited by Karl Rahner (and we all know that he made some errors). Was this a deliberate error on Rahner's part to further confuse us Roman Catholics or is there a story behind Pope Liberius that many do not know?
I ask that you please help me in this dilemma. Thank you.
