Hi strathos,
Yes, I've read all about Ellen White. I've even read a couple of her books. I get that SDA's have been the strongest denomination existing today that push the young earth understanding of the Scriptures. Although there are other denominations that are so inclined also. I come from a baptist background and it was fairly well accepted in my particular fellowship, although I can't say that it is some generally accepted 'rule' of baptist theology overall.
My point is not to deny the SDA's are the ones who are currently teaching young earth creationism, but rather your claim that it somehow started, or became a more popular understanding when they came on the scene. It is my understanding that in Judaism, young earth creation was pretty much the norm, certainly through Jesus' visitation to us.
Now, it may not be so today. I don't really know what the current mainline thoughts are in Judaism as regards age of the earth. I do know that their calendar is supposedly based on the year that Adam was created. So, if they believe what they themselves wrote 4500 years ago in the desert, then the mainline understanding is likely to be young creation. Of course, just as in christendom, there are different beliefs regarding this subject.
However, again I will say, for me and the evidence that I've seen, early christians, meaning 2,000 years ago and early Judaism had no problems with the young creation model and, I believe, believed it to be the explanation of the creation. My understanding is that the truth is that the belief in the two concepts, young creation and old creation, have merely reversed. We have gone from people of faith believing predominantly that the creation is young, to people of faith believing predominantly that the creation is old.
So, I'm just asking for your proof and I'm afraid that just saying that Ellen White championed the idea in her denomination doesn't really address what most believers understood about the issue 2,000-5,000 years ago.
God bless you,
In Christ, ted
