Who's in this group of people? Who decides who's in it? Who decides what the Bible is saying?
Answering "the Holy Spirit does" is taking the ignorant- easy way out.
The Bible is not all that Christ revealed and definitely not all that the Apostles set up. If they'd done that, they most certainly would have given us a list of Biblical Books to include as well as tell us to go by the Bible alone.
There is nothing in scripture to support your theology.
The Church is the pillar and bulwark of truth per scripture. Not the Bible. If the Bible was the pillar and bulwark of truth, than Paul would have called the Bible as such. Instead, he called the Church it.
You can read what their Disciples wrote about what they thought the Church was, or you can ignore it and pretend your scenario is truth.
THE CHURCH IS...
From a compound of G1537 and a derivative of G2564; a calling out, that is,(concretely) a popular meeting, especially a religious congregation (Jewish synagogue, or Christian community of members on earth or saints in heaven or both):- assembly, church.
THE CHURCH OF ROME HAS CALLED THEM SELVES OUT AND BECOME
From κυβ ερν άω kubernaō (of Latin origin, to steer); pilotage, that is,(figuratively) directorship (in the church):- government.
THE GOVERNMENT OF THE CHURCH IS UPON THE SHOULDERS OF CHRIST AND UNDER THE LEADERSHIP OF THE HOLY GHOST...
THE OLD TESTAMENT PROPHECY CONCERNING JESUS SAYS...
Isa 9:6 For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.
NOTE...IT DOES NOT NAME PETER OR A WARING.. ARROGANT... SELFISH... EVIL...EXCLUSIVE... ROMAN CATHOLIC CHURCH ....HERE
Isa 9:7 Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever.
GOD IS THE ONE THAT PERFORMS IT ...NOT THE CORRUPT ROMAN CATHOLIC RELIGIOUS SOCIETY
The zeal of the LORD of hosts will perform this.
