If there were intelligent aliens from outer space, do you think that the Catholic religion would apply to them?

"Intelligent aliens"? More intelligent than Steven Spielberg and Gene Roddenberry, do you mean?

Don't you have enough real, genuine problems to worry about without going Hollywood on us?

Cf. Matthew 6:34: "Sufficient to the day the evils thereof."

I think if humans were ever going to meet intelligent extra-terrestrial life we would have been warned about it by God in revelation somewhere.

Intelligent, rational (therefore in some way ensouled) lifeforms, with a view of right and wrong, abstract thought etc, showing up on planet Earth and having no knowledge of a Triune God would shatter my faith.  There would be too many "truths" that would have to be turned on their heads.  Not unlike believing in Vatican II and the new springtime.  You simply cannot square it with past belief and dogmatic teaching.  People who believe that Vatican II is right, must believe that the Church before was wrong.  Mutable truth is oxymoronic.

The idea that humans would have to convert a new planet of beings (and therefore, by inference, a whole universe of planets, like they did the American Indians would be a bridge too far.  Especially, since NOTHING like this is mentioned in the Apocalypse or anywhere even semi-credible for that matter.

Then there is the issue of Our Lady.  Not only is she Queen of the Angels but Queen of the Universe.  If there are 1000s or millions of planets with intelligent ensouled life out there, and the universe is a huge place, so if there is one there are many, then giving one creature from one planet the honours that Our Lady is given seems strange.  The Litany of the Blessed Virgin Mary would be a lie.

Our Lady cannot be "Queen of the Universe" just for the Solar System.  That is silly as the Universe is not the Solar System.  Nor can she be Queen of the Angels, because the Angels are not bound by the Solar System and would be the Angels of these other beings.  Once God starts having multiple Our Lady like characters, the Holy Morf, The Wonderful Hermit of Zarg it all gets a bit silly.

Plus Matthew's descendent could never moderate the intergalactic forum wars that would go on and CathIntergalaticInfo.com  So I'm agin' it.

Besides there is not one shred of evidence that ANY life even primordial slime, exists outside of the earth.  And goodness knows scientists would give their vital organs to find it.  Partly because they know it would underpin evolutionary theory and destroy what faith remains.  Generally speaking I don't speculate in Flying Spaghetti monsters existing until some pasta or tomato sauce falls out of the sky and makes a case for it.

Aliens might come to stop JPII's "canonization"

That might create a dilemma.

Anyway, if by some chance there is a claim that intelligent life has been found or has arrived here on earth and is being publicized by the authorities  one should first be 1) skeptical they are not some demonic deception that is contrived to deceive even the elect 2) understand that the Church has not ruled out the existence of intelligent beings on other worlds.

Catholic Telegraph of Cincinnati 1831 (first issue, I'm not endorsing this, just pointing out that these speculations are very old):

Whoever can follow the immortal Newton through all the wonders of this sublime Creation, will be induced, from fair and philosophical induction, to believe that they are inhabited, and that thus myriads of rational beings, perhaps superior to man, and rising regular gradations of perfection, up to the throne of God, form one vast innumerable host, who bend in thanksgiving and gratitude to that omnipotent power

Let's not forget that one speculation as to the cause of the fall of the angels was that the Incarnation was revealed to them and that they could not bear that God should become a man.

Aliens might come to stop JPII's "canonization."

Well, that certainly has a better chance of coming to pass than expecting +Fellay to give an interview to Der Spiegel in which he denounces the "conanization" (to borrow the sneer term of Traditio's Father Moderator) as a sacrilege.

If there were intelligent aliens they would have to be baptized if they were under the effect of original sin. The Catholic Faith applies to everybody.

Scripture and Catholic tradition should leave us quite confident that there are no rational creatures in the universe other than man and angel / demon.

The devil has power to work wonders in order to draw souls away from God. I wouldn't be the least bit surprised if there were some kind of governmental "alien disclosure" some time during my life. And despite the great temptation to the contrary it would engender, our job will be to ignore it and persevere in the Faith.

This thread might be seen as a sister to the geocentrism thread. The first step the world took toward pointless belief in life on other planets began centuries ago with the comological shifting of focus on our own world as the center of Creation to a focus on the nearest luminous heavenly body, of which our world became nothing more than one satellite out of nine (or is it eight?).

I disagree. Scripture says that God created the heavens. It did not explicitly exclude them from his creation. If they exist then they have to obey His law.

If there were intelligent aliens they would have to be baptized if they were under the effect of original sin. The Catholic Faith applies to everybody.

What if they had not sinned?

Anyway they may be tasty.  Martian burgers, mmm!
