I love Mormon logic. He was just speculating about His train, so therefore pay no attention to the fact that the speculation consisted of saying the train was His wife and children. Nope, no claim that Jesus was married there.
Kinda like how Lorenzo Snow's most famous blasphemy was "just a couplet". Apparently no more than one fact can be true about a thing at once. So if it's true that it's in couplet form, it can't also be true that it asserts God was once as we are now.
Don't you find it odd that denominations that don't claim prophetic authority for their leaders spend so much less time calling their leaders' comments "just speculation" "just a couplet" "speaking as a man", ect?
