Catholic Plan to Baptize Aliens

So what would happen if an alien ship landed at the Vatican?

No problem!!  The Pope says he would baptize them.

Just a few decades ago, we could only suppose the existence of other forms of life in the vast diversity of space. Today more than 3,000 exoplanets (planets which, like ours, are close to a sun) have been identified. Finding extraterrestrial life in the universe seems no longer a question of “if,” but of “when.”

So, just as a thought exercise, suppose a flying saucer landed in St. Peter’s Square during the pope’s weekly general audience. What would that mean for the Catholic faith?

As it happens, Pope Francis is three years ahead of us.

“If an expedition of Martians arrives and some of them come to us and if one of them says: ‘Me, I want to be baptized!’, what would happen?” the pope said during morning Mass in May of 2014.

Simple. For the pope of the peripheries, no matter how distant they may be, the Church does not turn others away.

The recent discovery by NASA scientists is not the first of its kind, and, in all likelihood, won’t be the last. For Jesuit Brother Guy Consolmagno, planetary scientist at the Vatican’s observatory and curator of the pope’s meteorite collection, extraterrestrial life is no threat to the faith.

In an 2002 interview with U.S. Catholic, Consolmagno even said he would be happy to baptize aliens if they wanted to. “Any entity - no matter how many tentacles it has - has a soul,” he said.

It's becoming more obvious all the time that "the lie" spoken of in 2 Thessalonians may include a whopper that consists of "aliens" telling us a new gospel that refutes the actual Gospel that Paul preached.

How would the Catholic church discern whether these "aliens" were actually fallen angels that Paul warned us about?

Galatians 1:8   But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let them be under God’s curse!
