Well, even pain during childbirth is possible if Our Lady offered to accept it. Without Original Sin, both Our Lord and Our Lady were also not subject to death and suffering in general, but both most certainly experienced both.
Absolutely not! Our Lady remained a Virgin before, during and after Our Lord's birth, therefore she gave birth miraculously, Our Lord came as the ray of sunshine goes through glass or a prism, it was a miraculous birth! To say that Our Lady gave birth normally, with or without pains, is a blasphemy...
Besides, the show has many other problems. It is paid for by Mormons and shows Our Lord with a human personality, which He didn't have. And I don't think it's respectful towards St Matthew either. Not to mention that the Romans never had an issue with Jesus! 🤦
