Hey, Orson Scott Card is one of my favorite novelists, and I am constantly chagrined that God had to raise up and prosper an LDS to honor His Son Jesus in a hostile venue.
However, I cannot recognize the LDS organization as a valid Christian denomination, and part of the unbroken continuity of God’s work on earth. They themselves assert themselves to be something new, a fresh testament, appearing in 1843 after Jesus turned His back upon His bride and stomped out for 15, 16, or 17 centuries.
That is certainly your right to chose and it is my right to think otherwise and question the validity of others.
