Quester, Jesus specifically singled out Peter (which would indicate a single, MAIN authority (not all).
Once again, even if this were true ... there is no Biblical mandate for Peter's leadership to last beyond his lifetime.
And take this analogy - If you but leave a house at a stand still, the elments like the wind would push and the wooden planks may become weak, therfore needing maintenance.
Foundation maintenance/repair is one thing.
Adding entire new wings not found in the original plan (i.e. veberation of Mary, assumption of Mary, papal infallibility, pugatory, indulgences, salvation of works, Transubstantiation, etc.) is quite another.
In that very same passage I sent to you concerning Peter, the Rock, etc. it says "...whatever you gain on earth will be gained in heaven, and whatever you loose on earth will be loosed in heaven." That is why the Pope is infallible, because obviously, heaven can not lose. Infallibility does not mean the Pope is absent from sin, speaks in perfect grammar, or says only the right thing all the time, every time. The Pope is only infallible when preaching on faith and morals. Now, this gets complicated; infallibility means "free from error," not perfection. So, in conclusion, the Pope when preaching on faith and morals is free from error.
You were the one that started the house analogy.
