It is interesting how you summarize things.
This is what I am saying:
Catholics claim they do not have continuing revelation. They claim that they preserve tradition. They claim to not CHANGE. Evidence that they change is evidence that Catholicism is not what it claims to be. To weigh potential CHANGES in Catholic doctrine is to investigate if the Catholic authority is in any way what it claims to be.
LDS do not make these claims. They claim to have access to continuing revelation. Changes can and will happen and it will not mean the same thing for CHANGES in Catholic doctrine.
Do you understand what I am saying? Do you agree with the above statements?
Development of doctrine is a sign of the living Church, but you should not confuse development of doctrine with innovation.
Truth was delivered once for all, in the Person of Jesus Christ. Through the ages we all seek to understand the objective Truth of the Son of God. Objective Truth is not subject to change. ie, our Object does not change, but our growth in understanding of the Object, certainly does.
It is Catholic teaching (both Orthodox and RCC) that through the Holy Spirit the Church, through the successors of the Apostles (our Bishops), grow in understanding. The Church is living, not dead, it is not a museum but alive in the Spirit.
So doctrines develop, and you will find enough written works, some by Newman who you seem to favor, regarding the development of doctrines. Newman, in particular, believed that if the Apostles would have accepted a current understanding of any topic (pick one), then the accepted understanding is Apostolic.
So, what does it mean that the Church is Apostolic, to you?
The LDS teaching that continuing revelation is a mark of the true church is a measuring stick that if applied to Catholicism quite simply proves Catholicism is not God’s church.
If I say to you, I hit a ball with a bat, does that make me a professional baseball player? If I say that I am a professional baseball player, wouldn’t it be wise to determine if a) I really do hit a ball with a bat, b) that I’m qualified to claim to be a professional baseball players and c) that I can actually show I do indeed play professional baseball?
Maybe you should take it on faith that yes, I do indeed play professional baseball.
Mormon Presidents fail all of these tests. a) Does a Mormon President really prophecy? b) What qualifies him as a prophet? c) What has been prophesied and when?
BTW, teaching from a pulpit does not qualify as prophesying.
I referenced above a “fallacy of fundamentalist assumptions.” Perhaps I should point out that some folks might place so much emphasis upon “consistency” that they do not believe a lack of consistency could exist within anything true. I think such thinking consistently applied results in some form of Judaism, but I can acknowledge it does not result in Mormonism. I also think such things are PART of what modern Sedavacantists suffer from.
Let me briefly mention that I personally reject the radical relativism that exists within some philosophical circles. At the very least I believe past necessity entails. This means that God either created human spirits ex nihilo at conception or spirits pre-existed before we were conceived. Both of these cannot be correct.
Of less import, I might say that either there is reason to hope for the soles of an unbaptized infant or there is no reason to hope for them. Or there is reason to hope for the salvation of Judas Iscariot or there is not. Our church leaders may change their opinions on these positions, but I do not believe God does.
Continuity is what is important to Catholics. From Adam to Jesus, we see continuity, what we call Salvation History. From Jesus to today, continuity in what is taught by the Church and professed by believers, is what we call Apostolic.
Heresies that arise, are known as heresies specifically because what is being taught or believed, is not Apostolic. ie, it exists outside of the continuity, from Jesus and the Apostles. Who knew Him, taught about Him and are witnesses to our Salvation.
Practices begun by actions of leaders may also change. Like married Roman rite priests or married priests in communion with the Bishop of Rome or no married priests in communion with the Bishop of Rome. Or priesthood to all worthy members instead of restrictions on blacks (or non-Levites).
Ummm, marital status is not something found in our DNA. A priest makes a conscious decision to not marry.
The problem with a 19th-20th century restriction on priesthood according or race or lineage, is that it doesn’t align to Christianity at all. It aligns to Mormonism.
