“The way I see it is there’s a Truth on every planet. All parts of the Big Truth. On a certain day they’ll all fit together like the pieces of a jigsaw. This has been a shaking experience. I’ll never doubt again, Father Peregrine. For this Truth here is as true as Earth’s Truth, and they lie side by side. And we’ll go on to other worlds, adding the sum of the parts of the Truth until one day the whole Total will stand before us like the light of a new day.”
The fire balloons are finite creatures, and that is enough to say that they are inclined to sin and are unable to lift themselves up to the power of God. This is another kind of relativism that makes no sense whatsoever.
But somehow the intelligent beings of other planets will encounter God, and He will save them. But no created being will ever become God Himself. All who are created are in need of God.
