Continuity mistake: Abner and Helah both have the stone cups that everyone else is using to drink the wine. The scene briefly cuts away, and then in a longer shot, you see Abner holding a goblet. The scene once again cuts back to Abner and Helah, who are now both holding the stone cups again. Throughout the wedding, a goblet makes an appearance in Abner's hand and is then replaced by a stone cup at various points. (00:48:10)
Factual error: Capernaum is shown as a town administered by a Roman prefect, patrolled by Roman troops. In reality, Galilee was a completely different jurisdiction from Roman Judea. Judea was under direct Roman administration, but Galilee was under a client king (Herod Antipas), and in that time the internal law enforcement was the task of the local ruler. There were no Roman legionaries patrolling the streets of Capernaum, nor was there a Roman governor of Capernaum or any city in Galilee.
