That is a false doctrine that the RCC has foisted on you. We can see just in the manuscripts that we have from these "Bishops of the Church" that they did not all agree and some even brought heretical ideas into the church.
What you should be trusting is the inspired word of God, which you seem to have a hard time doing. Did you ever play the telephone game as a child, if you did then you know how unreliable the spoke word can be. That is why us scripture alone Christians trust the written word. We have solid evidence from the RCC that they are willing to alter the word of God for their perceived benefit.
No. The Spoken Word of God is guarded by The Holy Spirit, it abides forever, it’s very different from what the private interpreters have fabricated.
Telephone is exactly what happened to the private interpreters, they compounded each other’s errors till none of them resemble each other.
Each adds their error over time.
Apostolic Tradition maintains the same interpretation and understanding.
I could go back to Augustine’s time 1600 years and we would share the exact same interpretation, doctrines and worship.
You could go back to Luther’s time 500 years and he would burn you at the stake as a heretic.
