<<If you want to shut up the Archbishop, please don't forget everyone else. No one should have to suffer through a political speech in Church.>>

Assuming you mean partisan politicking -- advocating for or against specific candidates, I agree wholeheartedly.  However, the preacher/homilist cannot entirely avoid the issues of the day, nor should s/he try to avoid them.  The maxim that the preacher "must hold the Bible in one hand and the morning newspaper in the other" has been attributed to Karl Barth.   The maxim contains more than a grain of truth, and implicit in it is an expression of how difficult the task of the preacher is.
