What beliefs would we consider reasonable for a self proclaimed Christian to hold?

[GrandizerII]

There's no need for divine creation when there is something in or about the universe that is eternal.

What you are saying is quite significant.
If science keeps going with those notions, it is only doing what was predicted over a 100 years ago, 1880's.
Science will be introduced to the ultimate way to make God of no consequence and obsolete.
This philosophy will open up the gates to discovering another aspect of matter, hitherto ignored by the vast majority.
People will fall for this, not just intellectually, but with every sense, because it will produce some mind blowing results.

Yeah, that "science thingy" sure disturbs the shit out of some theists.
