But many sources also speak about a Three Days of darkness, and other signs in the sky.  In the context of Our Lord's prophecies, to me it's clear that he isn't just speaking metaphorically, as He refers to various celestian events that would cause great fear.

I don't discount it. But I am sure you agree that spiritual realities are higher than temporal ones.

So the worse thing that could happen has already happened in the spiritual sense. Loss of faith, confusion, and error spreading, in-fighting among Catholics at all levels, and doctrinal and moral aberrations and poison flowing like spoiled milk and rotten honey from Rome (can honey go rotten?)

It is like how the Fathers say that it is a greater act of power for God to bring a sinner back to spiritual life than to raise a dead man.

OT it was reversed where the temporal figure alluded to the spiritual reality. After Christ, the law of grace elevates the natural and the figure gives way to the spiritual reality (though still veiled from human eyes) where the temporal manifestations really only serve to confirm the spiritual truth through miraculous manifestations of God's power to confirm the faith. think of the Miracle of the Sun.

Obviously these physical events can also serve to warn and punish as well.

So again, I definitely see times/celestial events as important, but IMO, the spiritual realities would need to come first and then these are confirmed by the physical signs.

Christ is the Sun of Justice and the moon (Church) receives Her light (doctrine) from Him, so spiritually we see the "eclipse" in the doctrines of the Second Vatican Council. A great and hideous beast emerging from the desecrated womb of the Church. Wear the Woman in the desert is the Heavenly Church that brought forth the infant Church under the Apostles that the dragon tried to devour. Now he has infiltrated into her inmost sanctuary (Palalu) and impregnated/desecrated Her (Hildegard) with this antichristic church that comes forth from her physical body, but not by her choice but as the result of Her rape by the devil. This or course, God has allowed partly not only as punishment for sin, but as the final fulfillment of the "mystery of inquiry" that Paul warned the Thessalonians about, which would only come to be once the "restrainer" had been removed, which many believe is the papacy. And temporally this is confirmed with our own eyes, as we have witnessed the innumerable public manifest acts of apostasy, heresy, and schism of epic proportions never before seen in the history of the Church and this coming from the alleged "Popes" after Vatican II no less - a great loss of "light". A truly spiritually terrifying event as if the moon itself had stopped giving off its light. Just think of all the chaos that would cause in the physical realm and this perfectly correlates to what has spiritually happened since Vatican II.

I think if we can pinpoint the spiritual reality of what has happened with the "eyes of faith" that this is much more important than trying to ascertain the correlating physical celestial movements, as those would only serve as temporally confirming signs of the greater spiritual realities that preceded these heavenly events in this particular case.

Thoughts?
