My good friend, The Monad, responded to my last post by writing,
"The question of what salvation would be on other planets is mind-boggling. I suppose if there is evil on those other planets than salvation is necessary...can Satan exercise dominion on other planets? What's to say that he can't? Then the question becomes one of soteriology. How does Jesus save? Is there something about the way in which Jesus brings salvation that is unique to this planet? We have no way of knowing."
The question indeed is of soteriology. If there is tripartite (mind, body and soul) life that is shackled by sin on other planets how are they saved? Are they saved?
My other good friend sees orthodox soteriology as being not only an anthropological but a cosmological panacea.
"The problems of finite-thinking have come about because of the belief that Christ's redemption ONLY applies to humans and not to rest of creation as well. Once we understand salvation as applying not to the salvation of souls but to the promise of the 'new heavens and new earth', the question about life on other planets and how they fit into the overall scheme of things, really is a moot point."
This answer isn't satisfying.
The value of reading Sagan is that we are challenged to strongly critique the entire anthrocentric enterprise. Christianity, wrongly or rightly, has a soteriology that is completely enthralled with the notion of humanity. Early Church history and controversy deal almost exclusively on the communicatio idiomatum.
Patristic thought may concede that Christ vindicated creation (universe and all), but they will stubbornly hold that specific salvation of humanity was only possible through the Incarnation.
St. Athanasius famously states, "He was made man, so that we might be made gods."
Poignantly, the soteriological question for St. Anselm was, Cur Deus Homo? or Why Did God Become Man?
Perhaps most provocative is St. Gregory of Nazianzus claim, "That which was not assumed is not healed; but that which is united to God is saved."
Extraterrestrials (a name for that itself is thoroughly anthropocentric) are not going to have a human nature. In that case, will their unassumed nature not be healed? If they are in every way like humans, except for having three eyes instead of two, will that third eye not be saved?
My friend writes,
"Sure the life, death and resurrection of the incarnate God happened in a remote corner of the universe, but that shouldn't limit its cosmic implications."
Well, of course it does!
The Gospel is the Good News. Thus, any good soteriology should be able to pass the scrutiny of the most important question for pastors: Is it preachable?
This is only conjecture, but Christian soteriology will probably not stir the soul of E.T.
On the other hand, if my good friend is right: God has vindicated all creation and creatures and promised a 'new heaven and earth' (or earths?). Then it seems that Evangelicals need to set new priorities. Forget Asia and Africa - there are as many as a billion worlds that need to know that God through Christ has given them new life! Evangelicals should become the biggest supporters of NASA, and begin a program to shoot bibles into space.
I'm not joking.
If one is convinced that Christ has undeniably, solely saved the fate of the entire cosmos one ought to feel an uncontrollable desire to rush headlong into the vast blackness of space only to hope to come across intelligent life and proclaim, "Christ has died, Christ is risen, Christ will come again!"
