Laura and @mitchellmckain,
There is good reason why this definition of infallible is not acceptable is this context. The context is Evangelical thought where the infallibility of God’s word has been defined by first the Fundamentalist papers and the more modern Chicago Statement.
Both of these positions indicate that the infallible Bible indicates that the universe was created in 6 days. Now I hope that the people at BioLogos know that the situation is much more complex than this. Unfortunately it seems that BioLogos has failed to come to grips with this issue so it continues to cause confusion.
The problems is this. In order to “defend” the Bible from the “attacks of science,” Conservative Christians felt that has to assert that the Bible is the Word of God, meaning that God dictated Genesis and the rest of the Torah to Moses. If the Bible is composed of the Words of God then they had to be Absolutely True.
The problems is that Jesus Christ is the Absolute Word of God. Jesus is the Way, the Truth, and the Life. He is perfect in that He is without sin, not that He is infallible in all knowledge.
The Bible is true and holy in that it is about Jesus the Savior, not because it is about science Jesus is the Logos, the Rational Word of God through Whom the Creator created the universe, so indirectly Jesus is about the universe or science.
