Who is David Grandland from Christy and what is their importance?

David Grandland is the mission's new minister. He has not chosen his place of service, but rather, has been assigned the Appalacian mission. The people of the mountain often reject his attempts to help them, but David is just as guilty of overlooking their culture and traditions when making suggestions. His sermons include difficult langauge and terminology, meaning that his parishioners often have no understanding of what he's saying. Fortunately, David's most evident intelligent, leads his parishioners to brand him the best preacher around.
