If you're cherry picking your good book according to modern scientific advancements to the point where your worship is completely heretic from the point of view of a priest from 400 years ago, and would be completely different from the theology of someone like you 400 years from now, it's time to reevaluate why you're even bothering in the first place

Either live by the whole book the way they used to or drop the book and be normal
