You concede the principle and are quibbling about the details. Was it you, or another, who denied Matthias is a bona fide Apostle who replaced Judas Iscariot as one of the Twelve Apostles, having met the criteria the bound by the Apostle Peter ?
Apparently, it has escaped your Catholicism focus that James was head of the body of believers instead of Peter. Rome is not the birthplace of Christianity. It was James who declared what would be the instructions to the gentile converts. Peter was the Apostle to the Jews and Paul the Apostle to the Gentiles. James was the leader of the body of believers centered around the location of the Temple, as Judaism shrank to insignificance with GOD's Spirit birthing believers, birthing them from above not from an institution.
And you have the meaning of bound and loosed all messed up under the religion of catholiciism rather than The Holy Spirit ... GRACE to men and women was loosed on earth and in Heaven (Rev 4:1).
Your man-made, satan directed religion would declare all manner of 'traditions' of your 'other gospel' are loosed by Peter's supposed Apostolic successors. Not one pope has ever been selected by Jesus; Paul was the last Apostle Jesus selected. Peter worked (casting lots no less!), Jesus Graced Saul in being selected. The Gospel is of Grace, not works.
