Interesting thread! I am an Eastern Orthodox Christian. There is so much we don't know about our world's beginnings! I heard a monk once describe a theory I had never heard before -- this isn't dogma, it's a theory: God lives outside of time. When God created man and man had perfect communion with God, man was outside of time as well. When man decided to disobey God, and break communion with God by eating the fruit of the Tree of the Knowledge of Good and Evil (on his own -- there are some fathers of the church that believe that God meant for man to eat of this tree when he had matured, but in the beginning man needed to first learn trust and obedience). When man decided to make his own decision to eat, apart from God, and when Adam and Eve did not even admit what they had done when God met with them that evening as usual, (they each blamed someone else rather than taking responsibility for their action -- who knows what might have happened if they had owned up to their sin at that point?) then -- according the monk I heard -- God created Time -- to give man time, and a lifetime to repent and return to Him.
What if when scientists are seeing these millions and billions of time in prehistory, they are looking at eternity through the telescope of time?
So -- I am not a young earth person or an old earth person -- I'm not a scientist, so I leave it to God. The Bible was not written to teach scientific truth -- it teaches spiritual truth. If we try to look at it scientifically, I think we can easily misinterpret what God is trying to tell us.
I also believe that we can touch eternity in this life, one moment at a time. God inhabits the present moment, and for now that is our access to the timelessness of God. If we spend most of our time living in our memories of the past, or planning for the future, we miss our opportunity to be present with God.
Anyway, that said, I see someone else brought up Wellness Mama's essay:Does the Bible Say We Should Eat Grains? - Wellness Mama which I'm referencing again because I found it so thought-provoking.
In my church, during the services we have opportunities to eat bread that has been blessed -- communion, antidoran (a small piece of blessed bread to make sure all of the communion is swallowed), Litya (in honor of a saint we may have a special service with 5 loaves of bread sprinkled with sweet wine and cut in pieces and handed to the people), and sweetened boiled wheat at funeral and memorial services (because Jesus said: "Most assuredly, I say to you, unless a grain of wheat falls into the ground and dies, it remains alone; but if it dies, it produces much grain." John 12:24). My husband and I have decided to stop eating grains at home and to only eat that which is blessed at church.
Now, there are quite a few people at our church who have developed Celiac, or other problems with wheat. To those, our priest gives the tiniest crumb of bread (we receive communion on a spoon from the chalice which has a mixture of bread, wine, and water), he says it is now the body of Christ and won't hurt you. The other forms of blessed bread are optional, and people may avoid them if they choose. Also, now at our coffee hour potluck after the Sunday worship service we have many gluten-free offerings since we have so many people sensitive to gluten. As time goes on, I expect this trend to continue.
The grain we have today, and the way we eat it today, is not the way it was done in biblical times. I see nothing against scripture by choosing to avoid modern grains.
