The definition of the word “day” is certainly important in deciding what to make of the Genesis account. In early times before there were accurate time keeping devices, a day was the time from one sunrise to the next sunrise. Most of us would accept that as a reasonable definition of a day. But consider the following from Genesis:
Then God said: “Let there be lights in the dome of the sky, to separate day from night. Let them mark the fixed times, the days and the years,
15
and serve as luminaries in the dome of the sky, to shed light upon the earth.” And so it happened:
16
God made the two great lights, the greater one to govern the day, and the lesser one to govern the night; and he made the stars.
17
God set them in the dome of the sky, to shed light upon the earth,
18
to govern the day and the night, and to separate the light from the darkness. God saw how good it was.
19
Evening came, and morning followed–the fourth day."
The question I have is this: If the sun was not created until the fourth day, How was a day determined? Early verses state simply that light was called “day” and dark was called “night.” They don’t say how long those periods lasted.
I know some people go to great lengths to make a “science” out of the creation story. I won’t say that it is a waste of time but it seems to me to be a far greater struggle than is needed to keep balance between reason and faith.
Scripture and sacred tradition state repeatedly that God is the God of creation. The Maker of all things, seen and unseen. Every rock, tree, living creature, drop of water, the mountains, valleys, planets, stars, etc. Close examination of all these things suggest strongly that, based on a 24 hour day, all these things appear to have been created over a longer period of time than 6 times 24 hours.
For me that presents no problem. I don’t look to Scripture for science lessons. Just as I don’t look to science books for wisdom, guidance or spiritual help. (For the record, I would far sooner put away all my science books than I would Scripture. Not because I think they are wrong, but because they just aren’t as important.)
I still make it a special point to rest and worship one day out of seven just as I try my best to keep the other commandments.
Getting back to the main point, a day can be defined in many different ways. Sometimes we may be uncertain as to how a long ago author really meant to defined it. I think it is ok to be uncertain of that. We have certainty on those things that do matter.
