Thank you for the link - it was a tough read but enlightening nonetheless. Still it pretty well validates the point I am making and that Catholics consider the Heavens closed for the types of revelation that would be used to guide the church after the fashion of which I am making in my comparison. Where we would differ in our understandings between what is revelation and what is not revelation is probably related to the Catholic concept of public revelation - from your link:
Thanks for actually reading it.

But as usual, you are applying what you want to see not what is there.
Christ’s Church is guided by the Holy Spirit. Period. You seem to be against the ways and means that God has chosen to guide His Church. I can’t say that an argument of, “you don’t do it like I want you to do it”, is much of an argument.
]The Christian dispensation, therefore, as the new and definitive covenant, will never pass away and we now await no further new public revelation before the glorious manifestation of our Lord Jesus Christ(see 1 Tim. 6:14 and Tit. 2:13).
Public revelation is the special revelation which God began with His direct communication with His inspired prophets and which ended with the death of the last Apostle (Saint John the Evangelist, around 100 AD). This public revelation is also known as the deposit of faith.
A bit more research examines what is currently considered public revelation and more clearly defines what types of revelation are included in the term:
- Sacred tradition and Sacred Scripture form one sacred deposit of the word of God, committed to the Church. Holding fast to this deposit the entire holy people united with their shepherds remain always steadfast in the teaching of the Apostles, in the common life, in the breaking of the bread and in prayers (see Acts 2, 42, Greek text), so that holding to, practicing and professing the heritage of the faith, it becomes on the part of the bishops and faithful a single common effort.
Please clarify if I am wrong, however it appears there are two components that rise to the standard of revelation and these include Sacred Scripture defined a is one of the several names denoting the inspired writings which make up the Old and New Testament.
Sacred Tradition or Divine Tradition, however reclaims the writings of the Apostalic Fathers and defines their origins back to Jesus Christ. It is not Public revelation but takes on sacred eminence by its origins as the exact traditions taught by Jesus Christ to his apostles and from these apostles to the early Apostolic Fathers.
The deposit of faith which Jesus Christ entrusted to the Church is made up of two parts: Holy Scripture, and Divine Tradition, this latter being composed of the truths passed down by word of mouth, and not written down till after the death of Christ’s Apostles and disciples, principally by the Fathers of the Church.
Sacred Tradition is the deposit of faith. It includes, most notably, the Liturgy, but encompasses everything that has been taught and handed on, and, the witnesses to the Gospel. This would include the lives and deaths (martyrs) of saints, art, parish records, etc.
Finally, for further emphasis of the current status of ongoing revelation since the time of Christ we can refer to this observation:
Divine Revelation was completed at the death of the last of the Apostles.
No, divine revelation has not ended.
Since that time
no new revelation has been made for the instruction of the whole of mankind. Whenever the Church decides a point of faith, it does so according to
Scripture or Tradition. It simply finds out what has been revealed from the beginning.

You diminish two things, which I suppose is occurring from your lack of understanding the high importance that is placed on them. First is: Jesus Christ is God’s Perfect Revelation. Everything is found in Him. I’m not trying to denigrate your beliefs, but I have yet to find a discussion with anyone who is LDS that can comprehend the importance of the Revelation of Jesus Christ to Christians (not just Catholics). We hold no belief that Jesus left something out, or forgot to convey something we should know, or hid anything from us. We believe, and trust completely, that the
fullness of Revelation is found in Him. So I will ask you what I have asked several Mormons posting to this forum: **What do you believe Jesus left out?
**
The second thing you diminish is the role of the Holy Spirit in guiding the Church that Jesus established on the Apostles. I don’t know the “remedy” for this, as I believe it is a psychological barrier to communication and understanding. I can only pray that the Holy Spirit guide you to Truth, Who is Jesus Christ.
And finally, there most certainly is new instruction, but this instruction will never change doctrine. What it does is guide the faithful in their current time and circumstance, as you know, these change.
An example would be in vitro fertilization. You may note, there is no guidance on this in Scripture. The Church has certainly given guidance.
Additionally, as to the current capacity of the Pope to declare doctrinal changes this falls under the definitions of Papal Infallibility:
Infallibility does not mean that the pope is inspired. Papal infallibility does not involve any special revelation from God. A pope learns about his faith in the same way that anyone else does–he studies.
This is an erroneous conclusion.
First, studying one’s faith is not an exercise that is separate from the guidance of the Holy Spirit. And second, the Holy Spirit guides Christ’s Church through
us, the Body of Christ. Us=all the baptized. Within the Body of Christ exist those who have been ordained to the Holy Priesthood. Gifts of the Holy Spirit are given to our clergy, which are many, but the one that is relevant to your understanding is the inspiration of the Holy Spirit in leading Christ’s Church.
The Pope is further gifted, as a servant of God, with the inspiration of the Holy Spirit in leading our Bishops.
That you don’t believe and understand this, does not mean that we (Catholics) do not.
If you’re up for some more reading, I recommend
Lumen Gentium.
Infallibility cannot be used to change existing doctrines or proclaim new ones.
It can only be used to confirm or clarify what has always been taught. The teachings of Christ cannot change. As the Scripture says, “Jesus Christ is the same yesterday and today and forever” (Hebrews 13:8).
So this puts everything in perspective so that we can make the comparisons, I was attempting to make in my post.
You haven’t supported your position. You’ve only stated what we believe, and applied your understanding to it, which is incomplete. Most notably you insist on leaving out the inspiration of the Holy Spirit.
However a brief mention of private revelation might be valuable so that we can clarify its implications to a member of the Catholic church as it relates to private revelation of individuals:
The Church does not propose them to us as part of her message. It is true that in certain cases she has given her approbation to certain private revelations. This, however, only signifies: that there is nothing in them contrary to the Catholic Faith or to the moral law, and,
that there are sufficient indications of their truth to justify the faithful in attaching credence to them without being guilty of superstition or of imprudence.
So, distilling this down the church does accept some types of private revelation which upon review are found to be acceptable to validation:
The Church gives her approval to them only when she is satisfied after rigorous examination of their spiritual utility and of the evidence on which they depend.
Thus when we distill this material down, and again correct me if I am wrong, but while the Catholic Church may not approve of the term the Heavens are Closed to reference the cessation of active ongoing revelation it nonetheless is the fact that there is no room to accept that there is any chance of ongoing revelation since the times of the death of John the Apostle. I freely admit that I do not have a Catholics understanding of these things and so welcome your insight, but as I read the material this is what I have concluded.
I think first it would help for you to understand:
Jesus Christ is the fullness of Revelation.
Jesus Christ is the Revelation that has never ceased.
However, I will concede that Peter makes it under the gun by your own definition. He could receive a divine revelation and actually change the direction and doctrine of the church as he falls inside the window of when revelation actually was permitted by Catholic definition. However, from an outsiders perspective and wading through all of the semantical implications I would still say that the statement the “Heavens are now closed” is a reasonable interpretation of the material from the Catholic resources you provided. If you would explain how that does not seem correct to you, I would appreciate it. Thank you for your insight, I believe I have a better handle on your understandings of when revelation ceased for the Catholic Church.
Still, an erroneous conclusion. But, if this is what you want to believe, so be it.
