I'm Catholic. First of all early Christians/Catholics did not read Genesis as literal but as allegory. I have a real problem with fundamentalists' interpretations.
Case in point: The following argumentative quote could have been written yesterday. Instead it was written in late 300AD by Saint Augustine of Hippo. He's chastising what we know call fundamentalist Christians Saint Augustine on Science and Scripture
The other point is Jesus was a man of his culture and followed his society's precepts. He was not omnipotent. If he was then he wouldn't have been "a man like us in all things but sin" as the verse says.
Just like acorns are very different from verities of acorn trees, wheat verities aren't created equal. The middle east had at least 8,000 years of hybridizing their strain of wheat. Speculation on my part but that was enough time to minimize the amount of gluten in their strain. Beer was being made in Egypt at that time so yeast was available to make leavened bread. Instead they ate unleavened bread. Maybe that was due to minimal gluten. Today, wheat is grown to increase gluten content.
Would I be putting a grain-feed cow on a fad diet if I took it out of the feedlot and put it on pasture eating the grass nature intended?
