See, I don't view that as arbitrary because that is what The Bible says. I thought you meant it was arbitrary to pick some point in the gestation period and say it's OK to abort before that point.
I don't think the Bible (Old or New) is nearly so clear on the point as you do. Passages of the Bible can be read to show that life begins before conception, at conception, or at birth (or, more precisely, upon the first breath).
But putting that aside, and assuming that the bible is clear on the point -- choosing to put absolute faith in a book is arbitrary, imo. Yes, I know, it is THE BOOK. But your belief that it is THE BOOK is itself arbitrary. By its very nature, faith is turtles all the way down.
