It is part of being a pastor, which requires study of the Bible, theology, and a hodge-podge of other things – including practical matters such as when to build or relocate as well as philosophy and art. I also took a degree in History. I come from book people. I once asked my father in law for a book on the Civil War, he went to a used book store and sent me a box.
