And do you feel that a consensus among the religion's body of leaders/members should not affect the overall teaching coming from that religious body?
Keep in mind, if you answer that "no, consensus should not dictate the teachings", then I'd present as evidence all the times when this sort of change has happened. Such as the great many changes and addenda to the Islamic religion made by Muhammad. The addition to the whole canon of Mormon Christianity by Joseph Smith. The many times the Catholic chuch (even in modern times) has reached a "verdict" on some issue they deem a moral imperative and come out with a public address as to their thoughts on the matter, and the teaching that should propagate from that moment forward throughout the Catholic church. The whole of Christianity (which itself is an adaptation of Judaism), and in modern times, the very Christian adaptation to coffee bars within churches, secularly-styled, live music played from a "stage" by a "band", and other things.
My point being, it is incredibly naive... and I mean "incredibly" - as in, you afford yourself absolutely no credit... to think that religions don't already adapt to the times. They just do so entirely too reluctantly, to the point that they seem to always be playing "catch up". Things change. You fall too behind, and you become irrelevant. Think Greek and Roman religions, now considered "mythologies" by the vast majority of people. And that's just an extreme example. As far as I have seen and heard news of, Christianity itself is seeing something of a crisis in our time. Churches closing, people leaving in droves. Their teachings ending up still being a bit too rigid for the liking of new generations, who have developed a different understanding of whether or not someone is allowed to dictate to you what is "sin" if the activity in question isn't hurting anyone directly involved. There is a foolish notion that "God will provide" even if they decide to turn their backs on anyone who believes differently than they do. I honestly hope they keep it up. I'd love to see Christianity go the way of the dodo. Perhaps it could be a wake up call to all religions to get their acts together, and start understanding that they don't, at all, hold the keys to knowledge and wisdom.
