Quote:"I vow to change nothing of the received Tradition, and nothing thereof I have found before me guarded by my God-pleasing predecessors, to encroach upon, to alter, or to permit any innovation therein;

To the contrary: with glowing affection as her truly faithful student and successor, to safeguard reverently the passed-on good, with my whole strength and utmost effort;

To cleanse all that is in contradiction to the canonical order, should such appear; to guard the Holy Canons and Decrees of our Popes as if they were the divine ordinance of Heaven, because I am conscious of Thee, whose place I take through the Grace of God, whose Vicarship I possess with Thy support, being subject to severest accounting before Thy Divine Tribunal over all that I shall confess;

I swear to God Almighty and the Savior Jesus Christ that I will keep whatever has been revealed through Christ and His Successors and whatever the first councils and my predecessors have defined and declared.

I will keep without sacrifice to itself the discipline and the rite of the Church. I will put outside the Church whoever dares to go against this oath, may it be somebody else or I.

If I should undertake to act in anything of contrary sense, or should permit that it will be executed, Thou willst not be merciful to me on the dreadful Day of Divine Justice.

Accordingly, without exclusion, We subject to severest excommunication anyone -- be it Ourselves or be it another -- who would dare to undertake anything new in contradiction to this constituted evangelic Tradition and the purity of the orthodox Faith and the Christian religion, or would seek to change anything by his opposing efforts, or would agree with those who undertake such a blasphemous venture."

Quote:According to traditional catholic resources, the “Papal Coronation Oath”, attributed to His Holiness Pope St. Agatho,  was taken by the popes of the Catholic Church, starting with Pope Saint Agatho, who was elected on 27 June, 678.  Over 180 popes, down to and including Pope Paul VI, swore this oath during their papal coronations.  Pope John Paul I, Pope John Paul II, Pope Benedict XVI, and Pope Francis who had no coronation ceremonies, clearly did not take the oath.
