It is always funny when God makes all these decisions that seem to benefit those that tell them to us and helps keep us all "stout observers of the religious doctrine".
ANY religion needs to be looked at carefully to see where teh true roots of many things began.
Some have valid social or even medical beginnings. Most, however, are political. One quest or protection of power, or a means and method to segregate and dominate your own clergy/flock.
I have little problem with a religion changing its doctrine, so long as that doctrine was not previously touted as an absolute stricture that must be followed lest you lose your balls in heaven (or on Earth if the reverend finds out it was you with his wife that last summer).
The key is to always take religion with a grain of salt. Not a pillar. Some may call that Pillar a Lot, I just say it is too much.
