As for Martians, Vulcans, Ferengi and miscallaneous theoretical ET's and LGM's -- they are a part of the Universe, which Scripture says was to some degree or in some way corrupted and "subjected to futility" by the Fall of Man. I don't know if this would be because they are related genetically to our race somehow, or if there is some other way entities become corrupted (that's all rather mysterious, isn't it?) ---- but IF they somehow lost spiritual gifts with which they would otherwise have been endowed, and they are, like us, a fallen race, then they would clearly need a Savior.
This is all speculation. C.S. Lewis, J.R.R. Tolkien, and Madeleine L'Engle all dealt with these themes to some extent in their Faith-influenced imaginative works. They didn't know either, but they thought about it.
I don't agree. An angel visited Mary at the Annunciation. An angel instructed and prepared the Fatima children for Holy Communion and he administered It to them (on the knees and on the tongue by the way).
They were not spiritually affected by the Fall of Man. Or, not that we know of.
Another false statement, I believe. Were not one third of the angels condemned to damnation due to the fall of man, thanks to Lucifer?
How do you know if Martians or Vulcans either beget or are begotten? You're beginning to sound like Francis and the resident wacko astronomer, Guy Consolmagno (another Jesuit by the way): "Any entity – no matter how many tentacles it has – has a soul." If Cocoa, the signing monkey, signed for baptism would Francis baptize it?
God created Adam, in His own image. God breathed a soul into Adam.
Both Francis and Guy seem to blow off Genesis as fairy tales ( with their support of evolution and all that "stuff"). Do you do so, also?
Where in Genesis did got create your Martians and Vulcans? Or do you, Francis, and Guy think the Holy Ghost left us an incomplete Bible?
