The official Vatican newspaper, L'Osservatore Romano, recently ran an article entitled, "The Extraterrestrial Is My Brother" in which Rev. Jose Gabriel Funes, director of the Vatican Observatory, told the paper that it was certainly possible that life forms could exist on other worlds, and that the existence of such life would not pose a problem for those of the Catholic faith.
Funes went on to say that if intelligent life existed on those worlds, they could be considered extraterrestrial brothers and sisters.
Although the concept of intelligent lifeforms on other worlds being our spiritual brothers and sisters might seem to be a new concept, it would fit well with the teaching of the Mormon Church which has taught this principle since its foundation.
It is also worth contemplating how this statement fits in with other statements or procedural changes that have been made in recent years by the Catholic church, specifically, the return to the use of Latin in the Mass, and doing away with the concept of Limbo.
