I love the LCMS but respectfully disagree with this position. The Bible clearly identifies God as the author of creation, but I do not believe Genesis attempts to make a scientific case as to how God created the world and the precise frame within which He did so. Luther routinely makes the case that we are to pursue excellence in our vocations as a way to serve others, and I would suggest that this teaching applies to those scientists who are trying to discern the age of the earth. The Bible does not hinge on a young earth interpretation, and we run the risk of telling scientists how to do science. It leaves us in a precarious position, as our realm is metaphysics, not natural science. Thank you.
