The prophecies of Fatima were approved by an official act of the Church under Pius XI's express consent in 1930.  The pope's exercise of his apostolic authority determines what Catholics must believe, not personal remarks by scandalous successors.

In the first sentence I hoped to express my belief that this error had been unwittingly repeated by well-intentioned faithful whose negative reception of the pope's recent action I have been edified by.

I suppose that is some kind of half-baked disclaimer/apology though you quickly segued into "lying" and "deceiving."

The presence of prophets in the New Testament was declared by God through St. Paul: "to another, prophecy," (1 Cor. 12:10), and also throughout the Acts of the Apostles. 

The verse you explicitly cited describes numerous charisms, but not one word of binding us to those gifts in men.

Our binding obligation to believe approved prophets is likewise expressed through St. Paul, "Despise not prophecies.  But prove all things; hold fast what is good." (1 Thess. 5:20-1). The 'proving' is accomplished by the pope, as defined by the Fifth Lateran Council.

"[P]rove all things… [including the prophesies in the preceding verse]" exhorts skepticism, not gullibility, not binding at all.

As the quote from the Catholic Encyclopedia expresses with excruciating clarity, we are not bound to private revelations. The papal approval only informs us that the apparition(s) do not transgress the Faith and the papal approval in no way binds us to the apparition(s).

We MAY safely believe in the apparitions. …There is no obligation to believe…

https://fatima.org/approvals-by-the-popes/

With the knowledge and consent of Pope Pius XI, on October 13, 1930 Bishop da Silva of Leiria (the diocese in which Fatima is contained) announced the results of the official inquiry of Fatima in a pastoral letter on the apparitions. This official approval contained these important paragraphs:
We MAY safely believe in the apparitions. This is what was conveyed to us, not by Pope Pius XI but by the Bishop of Leiria. There is no obligation to believe, though I do.

As you have made clear to me, my incompetence in expressing myself has blurred the distinction between the guilt of those consciously employing this error to stall the efforts of Our Lady's apostles, and the innocence of those who are unwittingly deceived by this error.

Some apology (pffft)—No allowance for Catholics of good will who recognize that objectively you are wrong.

You have adduced NO MAGISTERIUM that we are bound to private revelation.

You have adduced NO MAGISTERIUM that there is a "third" type of revelation.

The verse from Corinthians is God's assurance of the presence of prophets. 

So what? That is not news even to Catholic kindergarteners who know of the Prophets.

The verse from Thessalonians enunciates His binding command to believe approved prophets. 

You repeat your inference, a private interpretation. I repeat the antidote:

"[P]rove all things… [including the prophesies in the preceding verse]" exhorts skepticism, not gullibility, not binding at all.

Your inference is not consistent with the plain unambiguous language of the verse.

The passage from the Council enlightens us on how to recognize which prophets fall under God's command from Thessalonians.  The Council's wording makes clear that the subject in question is this third type revelation taught by St. Thomas. 

The phrase "public prophetic" does not appear even once in Session 11. https://catholicendtimetruths.com/fifth-lateran-council-future-evils-antichrist-judgment-day/12/07/2015

Quite contrary to your misrepresentation of Session 11, it is a lengthy and just diatribe against private interpretations reiterating exactly what your "opponents" say.


false prophets …Reliable report has it, rather, that they are preaching many and various things contrary to the teachings and examples which we have mentioned, sometimes with scandal to the people. …for their own self-display …that would make true the words of the Apostle writing to Timothy: For, a time is coming when people will not endure sound teaching but, having itching ears, they will accuмulate for themselves teachers to suit their own likings, and will turn away from listening to the truth and wander into myths. …twisting the sense of scripture in many places, often giving it rash and false interpretations, they preach what is false; they threaten, describe and assert to be present, totally unsupported by legitimate proofs and merely following their own private interpretation… what is more appalling, they dare to claim that they possess this information from the light of eternity and by the guidance and grace of the holy Spirit.

…When these preachers spread this medley of fraud and error, backed by the false testimony of alleged miracles, the congregations whom they ought to be carefully instructing in the gospel message, and retaining and preserving in the true faith, are withdrawn by their sermons from the teaching and commands of the universal church. … they turn aside from the official sacred teachings…

…the meaning of words is often lost when the hearts of the audience are bruised by too urgent and careless forms of speech.

…invented miracles, new and false prophecies and other frivolities hardly distinguishable from old wives’ tales

…We command all who undertake this task of preaching, or will later undertake it, to preach and expound the gospel truth and holy scripture in accordance with the exposition, interpretation and commentaries that the church or long use has approved…

…They are in no way to presume to preach or declare a Fixed Time for Future Evils, the Coming of ANTI-CHRIST or the precise day, (date setting) of judgment; for Truth says, it is not for us to know times or seasons which the Father has fixed by his own authority. Let it be known that those who have hitherto dared to declare such things are liars, and that because of them not a little authority has been taken away from those who preach the truth.

…nor that strange and empty predictions are matters which must be firmly asserted or held in some other way

Finally, after the long condemnation of private interpretation, a rather timid and very circuмscribed mention of prophesy:

Do not quench the Spirit, do not despise prophesying, we have no wish for them to be counted with the other group of story-tellers and liars or to be otherwise hindered. …credence must not be easily given to every spirit and, as the Apostle states, the spirits have to be tested to see whether they come from God. It is therefore our will that as from now, by common law, alleged inspirations of this kind, before they are published, or preached to the people, are to be understood as reserved for examination by the apostolic see.…

Nothing newsworthy or controversial at all:

• private revelation deserves great skepticism "tested"
• do not despise prophesy approved by the Pope (or delegated bishop)
• not binding at all beyond what is already in public revelation and the Magisterium
• the docuмent creates no "third" type of revelation.

Your own references reject your errors.


Such revelations are thus morally binding, in contrast with private revelations, which bind no one but the recipient.

Nowhere do any of your references bind us to private revelation per se.

In the practical order, the popes have decided to delegate the proving of public prophetic revelations to the local bishop, through whom, by extension, the pope approves these revelations, with the pope's specific, individual consent.

So what? Old news.

The crime of concealing the third part of the Secret of Fatima has kept Our Lady's message to us from reaching us.  We are bound to believe that it is Heaven's word, and the specifics within will be binding when we learn what they are.  Similarly, once we have read in Scripture that David was the son of Jesse, we are only then bound to believe it with divine and Catholic Faith. (St. Thomas, IIa IIae, q. 2 a. 5)

Though you repeat yourself ad nauseam, we are not bound to private revelation beyond what is already in the Deposit of Faith.
