Really?  The Creed is Dogma? That is what we believe?  Not anymore.  Some liberal churches don't even believe that Jesus is truly God. If they do believe that--they do not believe he is the only way to salvation.  Some churches believe in a Resurrection of the dead--yet not in body--thus rendering belief in the Resurrection utterly pointless.  

You sure that the creed is unchangeable--cause liberal Protestant churches have certainly changed the creed--or at least reinterpret it so as to bring it into line with liberal, secular atheistic humanism, thus rendering it meaningless.
