I understand your position as Catholic, that you firmly believe that the church’s interpretation of scripture is your only authority. I, on the other hand, see that as placing the church’s human wisdom above the word of God.
No, I am not cool with that idea at all. But I am in no position to judge, I am not God, so to lay guilt upon any individual is way beyond my authority. Institutions however are under no such protection, and if I believe an institution is guilty of anything, then I would not hesitate to lay blame if I deem it worthy or advantageous to any debate. I am not in this forum however to do any such thing, so I will not be drawn into a position where we both may end up regretting our words and causing friction and animosity where there need not be any.
I have seen it said often by Catholic apologists that if the RCC is in error, then Jesus failed therefore in His promise to keep the gates of hell at bay. But Jesus did not say that the church would be error free, but that the church would not be prevailed against. His promise is that the church would, in some form or another, survive. And that it did. Although the dragon, in the form of Rome, went to war against the church, (Revelation 12:17), and did certainly prevail over them physically in many instances, (Revelation 13:7) yet the church survived. As evidenced by the simple fact that we are talking over such issues today.
But remember, that the church of Rome was not the only church. Rome did not establish universal authority over other churches. Only in Europe, and then there were some notable exceptions such as the Waldenses who did not submit to papal authority. Elsewhere, the church lived on, in many cases having never heard of Roman jurisdiction and authority, such as in Africa, particularly Ethiopia, and the church of the East such as in India, Persia, and beyond. The Celtic churches in Britain for example existed 400 years before Augustine arrived there and found Christianity already well established by such as Patrick, Aidan, Dinooth, Finan and others. So apostolic truth flourished well in many parts of the world, quite independent of Rome.
