Mary has nothing to do with the fact that Jesus is God’s firstborn Son. He was God’s Firstborn millenia before Mary existed, before Abraham existed, before Adam existed, before ANYTHING existed.........
Again, I agree with you, but that isn’t what Mormonism teaches. They teach that God and Mary had sex and that Mary was one (just one) of God’s many wives.
Don’t you think that type of blasphemy should be responded too by Christians?
