The trailer is based off the Passion of the Christ, which might also explain its name. The video could be a hoax, but I doubt it. At any rate, I hope this movie is like the video series Jesus of Nazareth: based on the Gospels and spiritually wealthy. I hope it’s not like the Passion of the Christ: based on private revelations and spiritually a shipwreck (sensationalization of the suffering of Christ).
Interestingly enough, the movie title is very Orthodox: Mother of the Christ. Catholics call Mary the Mother of God, but Orthodox call Mary the Mother of Christ. Different theology, different terms. Still, the title could just be a tip of the hat to the Passion movie. We’ll just have to see!
