As I understand the Mormon church, (like the catholic church), has changed things over time. It occurs to me that faith and god would seem to be unyielding. as such, how can you explain a church, (as in the official position of a church), glorifying one position at one time and rebuking it at another? (I am not asking for specifics or any specific example because that really gets into the minutia.) I am just wondering, conceptually, how that is reconciled by followers in general?
