The Papal Oath you link to is the "updated" version of the 11th century. Previously, it had included different material, including the anthametization of Honorius.
Hermann,
How does the jec1ny version (above) compare to the 11th century version you mentioned as to the Pope being God's vicar? Was that in the oath in the 11th century? When did it become a part of the oath?
I wonder how Pope Gregory XIII rationalized his new calendar & paschalion in 1582 after having taken the above referenced oath or something very similar thereto. Before 1752, in England, Protestants had a field day with that. The Puritans gleefully quoted from the Book of Daniel: "And he [Antichrist] shall...think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time." (Dan 7:25 AV). After 1752, of course, the Puritans found they had to drastically adjust their thinking.
