The self employed preacher works part time filling in preaching at various churches when needed. He is always preaching a text from the Bible, and his purchased books further his understanding of the Bible, though not always regarding a sermon's specific biblical text. Under this worldview, ones growing knowledge of the Bible helps him to understand any text better as he undertakes studying various disciplines - biblical theology, systematic theology, biblical language translation/interpretation, hermeneutics, commentaries, etc. Are these expenses deductible for a seminary student or preacher when they contribute to a general or well rounded knowledge and not speaking to the specific text of a sermon/assignment?
