That’s rather an odd theory. It just assumes that whatever evidence you’ve found for an old earth must be correct because it is because any other evidence would be wrong, because it is. And God doens’t give wrong evidence !

It simply assumes one thing first and then says in effect “God wouldn’t be contradicting our findings of the evidence” because God wouldn’t do that!
Well, no. Let me add words to this (rather odd) paraphrase, since it didn’t really come close to what I was saying. This is closer: “Whatever evidence [meaning: empirically testable evidence] we’ve found [by scientific means] for an old earth must be correct because it is [empirically testable] because any other evidence would be wrong, because it is [contrary to empirically testable findings]. And God doesn’t give wrong evidence [this sentence, at least, does preserve what I was saying], because God is not deceptive.”
Let me try a different approach: Let’s assume (this would be a big assumption) that there is absolutely no creation story in the Bible for people to misinterpret, and never has been. So we have no history of the 6,000-year dating, the “young-earth” idea, the six literal days of creation, and so on. Based on that assumption, let me ask some questions (before writing long posts in reply, let me point out that these are yes / no questions):
- Would geologists arrive at the conclusion that the Earth is 6,000 years old, BASED ON THEIR EVIDENCE?
- Would astronomers arrive at the conclusion that the universe is 6,000 years old, based on their evidence?
- Would archeologists and biologists arrive at the conclusion that animal species have only been around for 6,000 years, based on their evidence?
- Would archeologists and anthropologists arrive at the conclusion that the human race has only been around for 6,000 years, based on their evidence?
Obviously, the 6,000-year “young-earth” idea is based only on a certain interpretation of the first chapters of Genesis, not on a reading of the actual evidence. (Before you start listing books by Jonathan Sarfati, Ken Ham, and the rest–I have them and have read them.) Furthermore, this interpretation of Genesis is not necessarily the interpretation held by the Catholic Church.
For example, go back 1600 years to Augustine. It is not the case that the Bible necessarily clashes with scientific discovery, but it perhaps is the case that scientific discovery clashes with some Christians’ interpretations of the Bible. And, as Augustine put it, when historical or scientific discoveries are found to be in conflict with our biblical interpretations, we should take a hard look first of all, not at the discoveries, but at our interpretations. In his article “Augustine and the Interpretation of Genesis,” writer Phil Dowe paraphrases Augustine’s position:
“There may also be external reasons for not accepting the literal interpretation of Scripture. This is where science enters the picture. These external reasons also rely on the premise that there is one God who has produced both creation and Scripture. This means that it is impossible that we should find science contradicting Scripture, or Scripture contradicting science. Augustine’s sense of science refers to that science which is conclusively proven and contradicts Scripture. In such cases, Scripture must be taken metaphorically. In fact, it is only in cases where science has been conclusively proven, that we may reinterpret Scripture. Augustine also urges that Christians must not be what he calls ‘doggedly literal minded’ in continuing to insist on a literal interpretation of Scripture in the face of proven science. He warns that Christians who do not take this advice will bring shame to their religion and its Scripture and prevent people from ever coming to accept what is important in Scripture.” (end of quote)
Contrary to some Young-Earth creationists, taking Augustine’s advice regarding the interpretation of Scripture does not mean we must place the authority of scientific findings over the authority of the Bible, as if God’s Word were “outranked” by advances in scientific knowledge. However, it is true that Augustine would place the authority of scientific knowledge over tendentious and arguable interpretations of the Bible.
SO: Before I’d be willing to continue on in this discussion, let’s have an answer to the four questions listed above. Yes / no?
