What does this interpretation have to assume?

Peter receives a real commission.

The Petrine commission is a permanent office transmissible after Peter’s death.

Historical succession evidence establishes continuity of that specific office.

The curated patristic sources document materially different emphases.

Counting or antiquity of fathers decides original meaning.

A continuing Petrine office exists.

The continuing Petrine office is uniquely located in the Roman episcopal succession.

Peter confesses Jesus and receives a personal blessing and promises in vv. 17–19.

Peter is the immediate singular addressee.

The sentence links Peter and rock lexically.

The exact referent must be Peter alone, confession alone, Christ alone, or another exclusive option.

Matthew 16:18 juxtaposes Πέτρος and πέτρα in deliberate wordplay.

The wordplay alone identifies one exclusive referent and later office.

Jesus says “my ekklēsia.”

The noun’s wider Greek range includes assembly/community usage beyond a later technical hierarchy.

The gates of Hades are said not to prevail against the church.

The metaphor must equal a specific later doctrine of institutional indefectibility.

Matthew 16:13–20 names no successor, transmission rite, Roman see, or post-Petrine office.

No explicit succession in this passage means succession is impossible from all other evidence.

Peter is promised binding and loosing authority in Matthew 16:19.

The keys of the kingdom are promised to Peter in the singular.

The keys are automatically hereditary and uniquely Roman.

Matthew 18:18 addresses binding and loosing in the plural.

Shared binding/loosing erases every distinctive feature of Peter’s commission.

Peter receives keys and singular address.

Binding/loosing also appears in plural in Matthew 18.

These data establish either exclusive supremacy or complete non-distinctiveness.

The bishop of Rome uniquely succeeds to Peter’s Petrine office.

That succession entails jurisdiction over every bishop and local church.

Vatican I explicitly formulates the Petrine → perpetual successor → Roman pontiff → universal jurisdiction chain.

Vatican I’s authority by itself proves every exegetical premise.

The Moscow Patriarchate explicitly affirms universal primacy of honor and rejects universal governing jurisdiction.

This one Orthodox synod speaks exhaustively for all Orthodox reasoning.

Calvin and the Westminster tradition document a confession/Christ-centered and anti-papal-headship formulation.

Reformation provenance itself proves the reading.

Petrine office continues.

Roman bishops uniquely inherit it.

The inherited office has supreme, full, immediate, universal jurisdiction.
