The Doctrine of Justification - why the Pope is the very Anti-Christ

In the news recently is the report of one of the presidential candidates leaving a Wisconsin Synod church because they teach that the Pope is the Anti-Christ. Much of the reporting shows a backpedaling on this doctrine by both the candidate and the Wisconsin Synod itself.  This leaves one to wonder whether the Wisconsin Synod (or WELS) believes this doctrine of the Lutheran Confessions or not.  The basis for this doctrine is biblical and those who backpedal from it show they are getting confused on the Christian Doctrine of Justification.  True Lutherans believe that we are justified by faith, not works.  Others get confused by thinking the papacy has returned to this foundational doctrine.  But it is not so... the Pope still teaches works for salvation.  Luther's warnings against the papacy are just as true today as they were in his time.
