Three things in response:
(1) It seems strange to me that you denigrate 'human reason' when your profile describes an you as having an interest in "systematic theology", which is a systematized process of studying scripture based upon "human reason".
No, I am denigrating human reason that does not recognize its own sinfulness and propensity for error. That does not recognize that their is a higher, infallible source, that all other sources of knowledge must bow to...
(2) The Galileo affair occurred about 500 years ago.
It seems that some in the evangelical church still haven't learned from it.
The Catholic church proclaimed, "the doctrine of the double motion of the earth about its axis and about the sun is false, and entirely contrary to Holy Scripture" (Pope Paul V - 1616).
False argument. The Pope was not actually getting what he said from scripture, but from Aristotelian physics. You are actually making the same error the Catholics made.... making "science" an authority equal to scripture. This is also the same error that led them to the doctrine of transubstantiation. The Church thought that they had to incorporate "science" into the scriptures, and so when the science moved on, they were left with so-called "infallible" papal decrees that they had to defend.
They should have trusted the scriptures to begin with, not science and flawed human reasoning.
Both scripture and nature are from God and both need to be interpreted; both science and theology are progressive in nature.
Scripture is not progressive at all. REVELATION was progressive, but the canon closed nearly 2,000 years ago.
2 Timothy 3:16-17 says scripture is sufficient. Thus, science is not needed.
Secondly, "natural revelation" according to Romans 1, can do nothing more than condemn a man for unbelief. There is no such thing as positive "natural revelation" that is authoritative in its decrees. SCRIPTURE is infallible and inerrant...human eyes, ears, and minds are not.
Science and theology can work hand-in-hand to help us formulate an accurate hermeneutical method.
This is probably the most frightful thing I have ever heard. You have in effect just elevated science ABOVE scripture.
Funny, how you assert that scripture must bow to human logic and reason, when Scripture asserts that human logic and reason must bow to scripture....
(3) Regarding the long ages of the patriarchs: the problem is unrelated to the age of the earth.
An old-earth creationist may handle this difficulty the very same way a young earth creationist might.
What is obvious is that the genealogies are not intended to be used as a chronology as you seem to suggest.
Rob
However they are "meant to be used" (something that cannot possibly be known), when the Bible says "he lived 900 years," then that individual lived 900 years.
So, this puts an absolute limit on the age of the earth, that does not come close to approaching 1 million years...much less billions.
