In, “Pope Leo the Great”, at the massive and very useful website “Triablogue”, John Bugay, and the late Steve Hays (June 2020) wrote some great analysis of this issue of the Papacy.
A Bridge Too Far
The mechanism by which all of this was supposed to have worked was a complete fabrication. As Steve wrote in his post entitled “Back to Babylon”, far too many things in this account are left unsubstantiated:
From Peter to papacy—a bridge too far:
Mt 16:18 is the primary Petrine text. But a direct appeal to Mt 16:18 greatly obscures the number of steps that have to be interpolated in order to get us from Peter to the papacy. Let’s jot down just a few of these intervening steps:
a) The promise of Mt 16:18 has reference to “Peter.”
b) The promise of Mt 16:18 has “exclusive” reference to Peter.
c) The promise of Mt 16:18 has reference to a Petrine “office.”
d) This office is “perpetual”
e) Peter resided in “Rome”
f) Peter was the “bishop” of Rome
g) Peter was the “first” bishop of Rome
h) There was only “one” bishop at a time
i) Peter was not a bishop “anywhere else.”
j) Peter “ordained” a successor
k) This ceremony “transferred” his official prerogatives to a successor.
l) The succession has remained “unbroken” up to the present day.
Steve provides an extensive analysis of each of those statements at that link. (Back to Babylon)
