Well, the problem is that almost everything is blatantly fabricated, even if they claim he has it, it was false or made out of 'whole cloth' as they say. We now have the Pope who makes up and pretends to have authority of believers and in the Church as the successor of Peter, to whom it is alleged that Christ exclusively committed the keys of the kingdom of heaven. But you have to understand that it was not so when the church began at Rome. Until the Pope was invested with the title, which for a thousand years had been attached to it the power of the keys of Janus and Cybele, no such claim to pre-eminence was ever publicly made on his part, on the ground of his being the possessor of the keys bestowed on Peter.
It was only in the second century that the worship of Cybele, under that name, was introduced into Rome; but the same goddess, under the name of Cardea, with the "power of the key," was worshipped in Rome, along with Janus, ages before in ancient times. For the first three centuries, the Roman Catholic claim for authority was founded simply on the 'dignity of their see', as being that of the imperial city, the capital of the Roman world. When, however, the seat of empire was removed to the East, and Constantinople threatened to eclipse Rome, some new ground for maintaining the dignity of the Bishop of Rome had to be found. So they fabricated it, when, about 378, the Pope 'somehow' fell heir to the keys that were the symbols of two well-known Pagan divinities at Rome. Janus bore a key, and Cybele bore a key; and these are the two keys that the Pope emblazons on his arms as the ensigns of his spiritual authority.
How the Pope came to be regarded as wielding the power of these keys took some time but that he did, in the popular view of church tradition, become entitled to that power at the period is certain. Now, when he had come, in the estimation of the Pagans, to occupy the place of the representatives of Janus and Cybele, and therefore to be entitled to bear their keys, the Pope saw that if he could only get it believed among the Christians that Peter alone had the power of the keys, and that he was Peter's successor, and this is what they di. Some time was allowed to pass away, and then for the first time, the Pope publicly assert his pre-eminence, as founded on the keys given to Peter. In 432, and not before, did he publicly lay claim to the possession of Peter's keys.
Now one interesting fact to note was that the Pontifex Maximus or Supreme Pontiff of the ancient pagan sun worship, bore the Chaldean title peter or 'interpreter'. the interpreter of the mysteries. So we see the opportunity to "Christianize" the office of Pontifex Maximus that the bishop of Rome now held, by associating the "Peter" or "Grand Interpreter of Rome", with Peter the apostle. Thus the stories about Peter being the first bishop of Rome, unknown and unheard of in the early church and earlier times, began to surface and 'claimed'.
Thus we may see how the keys of Janus and Cybele would come to be known as the keys of Peter, the "interpreter" of the pagan Mysteries, and we see the real origin of the authority of the Pope, and it wasn't from scripture.
