2 of V to DHK
I am so very glad you asked this. For I don't have the upper hand at all. I am just another man. But there is someone who does have the upper hand over both of us, Jesus Christ. And He established the Catholic Church. So it is that I appeal to the provision established by Christ which has "much greater authority" than either of us. As people, we're on equal footing. This is why, at best, Sola Scriptura is nothing but a private belief which you think (as a matter of opinion) I should accept, also. So according to Sola Scriptura our competing traditions do nothing more than "cancel each other out." Therefore, we, just as Christ indicated in Matthew 18, take our disagreements to the Church which has the authority to bind and loose, to forgive and retain sin, and to "cast out" the unrepentant sinner.
I may get to some of the other points raised later, But for now let's get right down to the basic core of disagreement. It is summed up in this paragraph which is:
The finality of the Bible vs. The finality of the RCC.
In your post here you say: "
But there is someone who does have the upper hand over both of us, Jesus Christ. And He established the Catholic Church. So it is that I appeal to..."
But this is patently false. There is no Catholic Church in the NT, and there never was. Furthermore you can't prove there was or is. You don't have the evidence.
Here is what you need to do in order to prove your premise true (according to RCC theology)
1. That Peter was a bishop in Rome. (He wasn't. There is on evidence he was even in Rome. His remains have been found in Jerusalem).
2. That the RCC Is a "church." It isn't. The word "ekklesai" applies only to local churches. The word means assembly or congregation. The Bible does not teach of a universal or invisible church.
3. That the doctrines taught now in the RCC are the same doctrines that were taught by Christ and his apostles (purgatory, indulgences, praying to Mary, assumption of Mary, acceptance of the Apocrypha, sinlessness of Mary, immaculate conception, confession to a priest, with the priest having the power to forgive, etc.
4. That there is a succession of Popes down to Peter--not of elected officials but of appointed officials. Elections are not successions. For example if Francis were baptized by Benedict VI who would have been baptized by John Paul II, who would have been baptized by Paul VI, etc. then that would be succession by baptism. There is no such thing as succession by election. Thus the RCC has no real succession does it? They just claim they do.
5. Show that they are infallible, as to the Catechism, the Magesterium, etc. The Bible says that "all have sinned and come short of the glory of God. These men are just like any other, and probably worse. My guess is that they were all unregenerate and none of them were actually born again of the Spirit of God. Those that are born again do not believe as they believed or commit such acts as they committed.
That is just for starters.
You have put your faith in an authority that is fallible and fails.
I put my faith in the author of the Lord God Almighty who cannot lie nor change, the One who gave to us His revelation, inspired and preserved to this day. I need no other authority but His.
