Er, one, holy, apostolic,
catholic
church. There is but one universal (
catholic) church, the invisible church comprised of those for whom our Lord came to redeem. Many visible vestiges of the Bride of Our Lord exist, the church militant, some more aligned with what He established, some not, some in name only. Rome, since Trent, lost any claim to being anything that resembles a church of Our Lord.
Which brings us back to:
When will you admit your malfeasance?
Then again, why am I not surprised given your wax nose about what you stand for...
Our Lord, in Matthew 16:18 most certainly does not mean that the Church will be built on Peter personally much less then through the bishops of Rome exclusively as his successors. Rather Our Lord means that the church is built upon
the faith confessed by Peter, that is, the person of Christ, His works.
So, yes, Peter is a rock in this sense only; a foundational stone of the church built upon word and preaching. The person of Our Lord is upon which the church is built as its cornerstone, see (1 Cor 3:11). Just as in Ephesians 2:20, using the same language it is clear the church is not built upon Peter exclusively but upon all the teaching and preaching of the prophets and apostles as found in the NT.
And
the "keys" represent the authority to exercise discipline in the church and to open or shut the kingdom of God of God to men by proclaiming the gospel and the conditions for receiving forgiveness of sins.
Despite your claims to superior knowledge, you simply have no facility with the history of Romanism or the teachings of the ECF, so you have simply swallowed what you have read here and there from Rome and its apologists. Would that you turn that vast intellect of yours towards an unbiased reading of history and the ECF, and you will, if you are honest with yourself, realize that all is not what Rome claims.
