Tenable? Maybe,but is it true? Don't forget the obligation as a Catholic to hold as truth the Infallibility of the Pope in regards to faith and morals.
I think there are many more instances in the new testament providing examples of Peters Primacy among the apostle, even if some wish to deny what seems to me fairly conclusive proof of his infallibility, which flows from the charism of his office.
I will not post all the quotes, for I don't have time right know. But I'm sure the rest of you well informed RC's can supply.
Good catch! I meant to say that the two positions can not be reconciled.
