If there are species, and rational species, other than man, are any or all of them, like us, fallen? This is the point non-Christians always seem to forget. They seem to think that the Incarnation implies some particular merit or excellence in humanity. But of course it implies just the reverse: a particular demerit and depravity. No creature that deserved Redemption would need to be redeemed. They that are whole need not the physician. Christ died for men precisely because men are not worth dying for; to make them worth it. Notice that waves of utterly unwarranted hypothesis these critics of Christianity want us to swim through. We are now supposing the fall of hypothetically rational creatures whose mere existence is hypothetical!
