Today he posted on a thread about the speed of light as a challenge to Young Earth Creationism. He gives three possible answers to the challenge and pretty much concludes that the fact of the speed of light does indeed defeat the Bible:
1) the simplest answer: God created light in transit. But when one considers the vast amount of information which is contained in the light from a star, this makes God seem deceptive. (The spectrum tells us elemental composition, recessional velocity, rotational velocity, etc.) Thus some YECs have said this argument should not be used.Why isn't it immediately apparent to a generally good head like Dr. Bertsche, who does seem to be a true Christian, that what fallen humanity is able to think cannot be made God's judge?
2) another answer is that the speed of light was much faster in the past. But the main evidence for this is an imaginative analysis of historical data by Setterfield, which has been questioned even by other YECs. Again, some YECs have said that this argument should not be used.
3) Jason Lisle has recently proposed an imaginative theory, that the speed of light moves instantaneously toward an observer, and at 1/2 c away from an observer. He claims freedom to do this because he believes that we can only measure the round trip speed of light, but not the one-way speed of light. But in this he is wrong. We have good measurements of the one-way speed of light, and devices such as particle accelerators and free-electron lasers would not work if the one-way speed of light were not c.
I think the speed of light is a good issue to raise with YECs. I have a YEC friend who became an OEC ("old earth creationist") after thinking about the explosion of SN 1987A.
The only right answer to this challenge is that we don't know how God did it -- perhaps one of the current YEC theories is correct for that matter though obviously it's not easy to determine that -- but if we believe God's word it is certain that NOTHING in His universe is going to contradict His Word.
This is only "a good issue to raise with YECs" because we don't have an answer to it, so it gives us the choice of rejecting science, which is cause for endless jeering by the unbelievers, or capitulating as his friend did who became an Old Earth Creationist. So by saying that, Dr. Bertsche shows his bias in favor of science against God. We have these and only these options: Choose against science or choose against God. Why is it that so many choose against God? WAY too much trust in our current state of knowledge and in the fallen human intellect.
No, issues we do not know enough to answer in a way that supports God's word have to be left alone. We have plenty we can answer very well, and if those were taken seriously they should in themselves force an honest person to rethink such claims as converted kbertsche's friend.
