Just for fun, ask someone to name the theme of the last 4 Sunday talks given. Or ask them to summarize the previous chapter in the Congregation "Bible Study". Easily 98% will not be able to do it - yet the meetings are supposed to be so utterly "vital".
In my congregation, they won't even know the theme of any of the last 4 Sunday talks -- and that's two hours after the meeting. And I mean that!
