... Can’t find “peters throne” in Christ’s words...
Man's always tried to dethrone Christ's rightful place, manufacturing even Himself to be there...and if not his idea of finding a way to upsurp Him by someone or something else...then use him like a tag line.
"But there are also many other things which Jesus did; which, if they were written every one, the world itself, I think, would not be able to contain the books that should be written." John 21:25
Pure stupidity. The throne is the throne of the bark of St. Peter. Christ is the tree and we are its branches.
The expression “power of the keys” is derived from Christ’s words to St. Peter (in Matthew 16:19). The promise there made finds its explanation in Isaiah 22, in which “the key of the house of David” is conferred upon Eliacim, the son of Helcias, as the symbol of plenary authority in the Kingdom of Juda. Christ by employing this expression clearly designed to signify his intention to confer on St. Peter the supreme authority over His Church, that there be one Church, one teaching of his Word, and His Body and Blood will be found in the Holy Eucharist. All the rest emanate from the Eucharist. The Eucharist is the throne and its celebration in the Mass is through St. Peter, his Apostles, and his consecrated disciples.
The rest is all Benny Hinn, Bishop Jake, Joel Osteen, Rev. Schuller, Rev. Wright, Tammy Baker, your local Foursquare Church Pastor, etc,
The Chair is, in its essence, a metaphor/symbol of authority and each Catholic Bishop has his Cathedral with its chair (cathedra) of authority as does the Pope whose Chair/Throne of Peter is in Saint Peter's.
