Actually the difference is that most of the preachers you think are great, you also consider them to be preaching infallibly. The pope, only rarely (less than ten times in the last millenia) is said to have spoken infallibly. You put more power into the hands of your preacher than Catholics do the pope.<quoted text>The difference is that Preachers are taught about in GOD'S instruction manual. The Papacy is not.
As I said, you don't know what the pope is.
