Sometimes, mountains for some people really are molehills (or even plains) for others.
For those who struggle with any particular aspect of church culture or doctrine, it does nobody any good to take what is a natural molehill for someone else and turn it into an artificial mountain.
Likewise, different people have allergic reactions to all kinds of different things, and the same is true of reactions to various types of food.
For those who don't struggle with any particular aspect of church culture or doctrine, we might love something very much (and it might even be our favorite), but it would be silly to try to make someone else try it if they were allergic to it or would have some other type of negative reaction.
Learning to celebrate differences, even ones that we don't really understand or think are not ideal (as long as they are not highly destructive of community), is very liberating - and it's the type of Zion I envision.
