It`s a commitment to regress.
Dark Ages were the golden age of Christianity - pope had the authority over whole of Old World in one way or another. Hell, Papal bulla had formally given Spain all the rights for New World.
Now, ask yourself... Why the ages were called DARK?
Actual advance began again after people began to ignore the opinion of church. Ever since then, history shows abundantly clear how church`s power had been whittled down to make advance possible.
Religion is openly destructive and regressive concept, with no redeeming qualities. It panders to lowest and loftiest feelings of humans, takes advantage of their weakness and stringently opposes any and all attempts to liberate people from the misfortunes that their weaknesses cause.
Abject misery is the lifeblood of church, the reason why it can continue existing. In a world where everyone is safe, sated and warm, no consolation from "higher forces" would be necessary, and therefore, misery will never end while the religious have any say on the matter. Advance all that you can, but religion will create the aforementioned misery if not beaten down ruthlessly at the merest attempt to.
