Dear Ken,
Has no one explained to you that one can as little compare the biblical creation story and a scientific theory like that of evolution as one can compare, shall we say, an organ and a vacuum-cleaner—that there can be as little question of harmony between as of contradiction?
The creation story is a witness to the beginning or becoming of all reality distinct from God in the light of God’s later acts and words relating to his people Israel—naturally in the form of a saga or poem. The theory of evolution is an attempt to explain the same reality in its inner nexus—naturally in the form of a scientific hypothesis.
The creation story deals only with the becoming of all things, and therefore with the revelation of God, which is inaccessible to science as such. The theory of evolution deals with what has become, as it appears to human observation and research and as it invites human interpretation. Thus one’s attitude to the creation story and the theory of evolution can take the form of an either/or only if one shuts oneself off completely from faith in God’s revelation or from the mind (or opportunity) for scientific understanding.
Yours,
Uncle Karl
