Infallibility and Pope Sixtus V

The Infallibility of the Bishop of Rome and the Comical Case of Pope Sixtus V

By Presbyter Basil A. Georgopoulos.

On July 18, 1870 at the 4th conference/1/ of the 1st Vatican Council – considered as the 20th Ecumenical Council by Roman-Catholics – after a long historical gestation,/2/ and amidst opposition,/3/ Pope Pius VIII read the decree Pastor aeternus/4/, by which he recognized the infallibility of himself and all his predecessors and successors as a truth of faith revealed by God.

Of course, for Orthodox theology,/5/ the infallibility of the bishop of Rome belongs to the sphere of papal mythology. Not only does it lack the mark of a dogma but at the same time it constitutes an arbitrary and blasphemous appropriation of a distinctive trait and characteristic of the theanthropic body of Christ, the Church.

A true testimony to the above is the verdict of ecclesiastic history. One of the many examples of how infallible the predecessors of Pope Pius VIII were, is the comical case of Pope Sixtus V (1585-1590) and his edition of the “Vulgata” in 1590.

Pope Sixtus V, encouraged by the decision of the Synod of Trident/6/ where the “Vulgata” was recognized as an authentic article of the Roman-Catholic Church, issued and distributed a new edition, historically known as the “Sixtina” edition./7/ In the papal decree in which Pope Sixtus V announced the edition, he mentioned that the said text would be the only authentic text, and this seeing as this text had been corrected “by the same hand grounded on the authority of the abundance of apostolic power.”/8/ He also ruled that every other publication of the Holy Scriptures lacked value and whoever tried to overturn the new text would automatically be excommunicated.

Two years later, Pope Clement VII (1592-1605) retracted the edition of Sixtus V because it was full of deceit and errors in “translation, expression and teaching.”/9/ In fact, the Jesuit Cardinal Robertus Bellarminus – one of the greatest papist theologians to date, a saint to the Roman-Catholics and great supporter of papal primacy – characterized the article of Sixtus V “as a labyrinth of deceits of every kind.”/10/

The same Bellarminus in fact mentions in his autobiography that he had asked Pope Gregory XIV (1590-1591) to protect the reputation of Sixtus V from derision. How? By re-issuing his 1590 edition corrected and with the addition of a prologue by Bellarminus in which he would explain to the faithful that Sixtus V was not to blame for the errors but the “printers and others.”/11/

This event itself, as well as the actions of Bellarminus, reveal how infallible Pope Sixtus V, a predecessor of Pius VIII, was. As a final comment in this short article, by what is shown in the case of Sixtus V in relation to the infallibility of the bishop of Rome, we wish to mention the perspective of the Patriarch of Jerusalem, Chrysanthos Notaras (1707-1731). He attests to “the innovations of the Western Church, and the present new and recent monarchless monarchy and sinful sinlessness of his colleague (if I can call him such) in Rome, which the Holy Fathers of both East and West neither knew, nor even imagined, as they are novel and strange seeds, and inventions of the Western Church, sown and planted with a spirit of pride, and immoral arrogance, and having taken root for an extended time have brought forth rotten fruit.”/12/
