Well, the Fathers of the Catholic Church were good at these gymnastics.
Let us look at a quick summary of the way that the Church Fathers interpreted that verse -
**“Thou are Peter and upon this rock…” **
Archbishop Kenrick of Saint Louis, who was one of
America’s extraordinary bishops was at the the
First Vatican Council in 1869 and he went to the
trouble of lining up the Church fatrhers and how
they interpreted “Thou art Peter and upon this rock…”
In his speech prepared for, but not delivered in, the
Vatican Council, and published at Naples in 1870,
he declares that Catholics cannot establish
the Petrine privilege from Scripture, because of the
clause in the Creed of Pius IV, binding them to
interpret Scripture only according to the unanimous
consent of the Fathers.
And he adds that there are five different patristic
interpretations of St. Matt. 16:18
Let’s look at how the Church Fathers line up over this verse:
1…“
That St. Peter is the Rock” is taught
by
seventeen (17) Fathers
2…That
the whole Apostolic College is the Rock,
represented by Peter as its chief,
is taught by
eight (8) Church Fathers
3…That
St. Peter’s faith is the Rock,
is taught by
forty-four (44) Church **Fathers **
4…That
Christ is the Rock,
is taught by **sixteen (16) Fathers **
5…That the rock is the whole body of the faithful.
Archbp. Kendrick gives no figure.
Archbishop Kendrick summarises
“If we are bound to follow the greater number
of Fathers in this matter, then we must hold
for certain that the word “Petra” means not Peter
professing the Faith, but the faith professed by Peter.”
You can look this up and check that I have
it accurately in Friedrich, *Docum ad illust. *
*Conc. Vat. 1, pp. 185-246 *

Now in light of the fact that the large majority
of the Church Fathers do NOT teach that the Rock
is Saint Peter, I say that it is not fair if we think that
people who also do not accept it guilty of mental
gymnastics. Are the Church Fathers guilty?
