How can we understand the differences between ‘knowing’ and ‘understanding’?

There has been a lot of talk recently about the role and ordination of Women in Churches throughout the world and Church bodies are taking more of a stance one way or the other. The church bodies that do not ordinate women are conservatively minded and claim to have special knowledge on the understanding of the church that their god or prophet claims it to be. On the other hand, the churches that are embracing the ordination of women have this understanding that the world has changed and that women need to have a larger role in their churches. In some ways, women need to take more leadership positions because women tend to be more spiritually inclined than men. On the whole, it is better to be understanding than it is to claim to have special knowledge of the way the world should work. Knowing and Understanding define the divide between ‘liberals’ and ‘conservatives’ and a myriad of other divisions. Is it better to ‘know’ or to ‘understand’? In my experience, it is much better to understand than it is to know.
