“Then why do Catholics quote Scripture to give the Church and Peter their authority?”
Catholics quote scripture to prove that Jesus Christ gave St. Peter this authority and founded his Church.
Again - it is not the bible that grants them this authority, but Christ himself. The bible - as an accurate testimony of Christ’s teachings serves as our witness to Christ’s mission on earth. Part of which includes the disciples and the founding the Church with the Apostles, Pentecost, and the coming of the Holy Spirit in Acts, etc.
Again, all these things happened before even the first Gospel was written.
By your own words you are saying that you use circular reasoning, so why should we believe anything the Church has to say about anything?
The bible was written by the Church to prove the Church is the only way to salvation. Joseph Smith wrote the same things.
As soon as you claimed the RCC is more authoritative than God, you lost all respect, and entered into cult status. I have long suspected that the RCC was a cult, but this just cements it.
The "Bible" contains more than just the books written after Jesus' resurrection (the OLD Testament). You acknowledge this, right? Some of the Epistles in the New Testament were written years before the Gospels but the Gospels are the written testimony of what Jesus said and did while here on earth as the Holy Spirit brought back to the remembrance of those who God commissioned to write the accounts. Jesus' teachings learned by His Apostles and disciples were taught around the world and those SAME teachings were written down, also under leading by the Holy Spirit. That is exactly how the believers in the centuries after those first believers died could still know the correct doctrines that make up the rule of the Christian faith. Whatever the church teaches MUST line up with what Holy Scripture says else it is not holding to the teachings delivered to them by word and by writing.
