Of course, that's the big problem with treating unsupported assertions as fact, and declaring that one is "unshakeable" on this. If
your religious leaders suddenly do a complete
volte face, you have two choices:
[1] Remain "unshakeable" with respect to the assertions in question, and launch a schism;
[2] Follow your religious leaders, and hope no one notices that you weren't as "unshakeable" on this as you declared.
Of course, the situation is even worse for the religious leaders in question, who don't have the benefit of public anonymity that their followers have. Who have all the fun of explaining why assertions previously treated as immutable tenets of doctrine are now suddenly being abandoned.
That's another reason to prefer science to religion. In the world of religion, being wrong is an embarrassment to be avoided at all costs. In the world of science, being wrong is frequently
a research opportunity.
