No, it is not. You are confused. Jesus is Jesus is Jesus. Joseph Smith claims Jesus came over to the Americas. Same Jesus as the one on the Cross. SAME JESUS. You need to do some homework and quit being so judgemental.
Well, there is no proof that that happened.
I'm sure it would be supported by the Bible if it was true.
It wouldn't be the first thing that Joseph Smith lied about.
So because Smith claimed it, you believe it?
