What is it that has Christians so spooked about the book or movie? That Jesus had a wife and children? So what? If he had a wife and children, and still was resurrected, then there's hope for the rest of us.
It just isn't true.
The fact is - that many will believe the fiction or it will put doubt in their heart.
We live in an ignorant society. Why would Christians choose to participate in something that will work against what the Lord wants?
Another thing - the Jews never accepted that Jesus was the Savior. Therefore, they are not dishonoring their Savior as they do not accept He is the Savior. But I do and it is just another slam against my Savior.
Again, why in the world would I want to pay money to see it? If I go to church to worship Jesus - why would I go to a movie that dishonors Him?
