Vast Universe: Extraterrestrials and Christian Revelation, by Thomas F. O'Meara OP. Liturgical Press, 2012.
"My God, how great thou art!" These are the words that best sum up the focus of this book by O'Meara.
These are some of the questions that the author aims to answer in this small book:
a)
Are there other worlds?
b) If there are , are there humans dwelling on them?
c) Is it against the faith to believe that God made other worlds and inhabited them with humans?
d)
Did the Holy Trinity stretch out in ages past and set to redeem other worlds after they had sinned? Each person of the Trinity taking a different world? Or did those planets remain sinless?
e) Would it bother you if there were humans on other planets?
f) Why couldn't God incarnate Himself on another planet?
At the end of one chapter, O'Meara says: "The idea that there are intelligent persons on distant planets is not completely new. A few philosophers and theologians have presumed that such creatures exist. Extraterrestrials are not rivals to people on Earth but expressions of divine power. Sin, person, and grace do not necessarily have the same forms in different worlds, and Jesus, a central figure in Earth' s religious history, is not repeatedly incarnate. Time and distance separate one planet from another, and they also separate faiths from religions."
Intelligent life in the universe, not just on earth, has long been a topic that Christian thinkers have studied. Here are some thoughts of Protestants: A Lutheran theologian said that Christ's incarnation could have happened many times in many areas in the universe. Another said that Christ could only have died and been resurrected once. Thomas Paine thought that a Supreme Being populates planets, each of which had an Adam and Eve plus an apple, and needed a redeemer. Jesus did that from place to place. One writer contended that the Word of God went about from planet to planet, found sin, and became incarnate to save the human race. Paul Tillich maintained that man cannot claim he occupies the only possible place for incarnation.
Some Catholic theologians maintained in the 19th century that extraterrestrials do exist and that does not demean or limit Christ. Whether they sinned or not is uncertain. There are analogies between Earth and the planets and stars, and that array of stars and their ability to change, argues for other populated worlds. Some studied Mars and argued that it is capable of sustaining human life. One said that other planets have life in a natural state of happiness, and even if the inhabitants sinned, they could be redeemed. Karl Rahner writes: "God is free to fashion other worlds, worlds of different types. From this point of view, there is no veto against a history of free intelligence on another planet."
In conclusion, here is the wisdom that comes from a theologian who had been active in Vatican Council II. Yves Congar states: "Revelation being silent on the matter, Christian doctrine leaves us quite free to think there are or there are not other inhabited worlds. Earth should not limit divine power. There may well be other incarnations of the divine persons of the Trinity in finite persons."
