I dont think I could reject either. I think the beauty and love displayed by Christ through salvation, is something that no person could really live without. Despite there being non believers in the world, the moral lessons and truths in scripture, I think are wholly truthful and cant really be rejected.
Scientific evidence on the other-hand, well, it is as true as the sun is bright. It is creation, as is the word of God.
So, i dont know that I ever could reject either. One could not be sacrificed for the other either, one could not take place for the other.
I guess thats why we are all in this boat of theistic evolution. We (those who are TEs) don't have a choice, or perhaps do not think we do.
