Across the board there are only two kinds of preacher. There is the vast majority who talk about the Bible, about religious stuff, and other issues. Then there is the preacher that explains the Bible. These two types are found in every denomination without exception. It appears that in places like Rome and the Eastern Orthodox, there is little to no Bible preaching, what you get is talks about tradition, what this father said, what that ceremony of for, the PC agenda, and so on. Among Protestants you get the same thing, just in different words, but there are also the actual expositors of the sacred writings.
Only the second kind is doing his job.
