Nary Magdalene as one of the apostles, traveling around with 12 men? Or was it 13? Did they replace someone or just add her. I didn't count.
If they are to do a Jesus mini-series, I hope they keep closer to the source material. There was to be some filling in the gaps, of course, for instance, anything that Joseph says, but it should be stuff that is inferred in the text or the epistles and not pablum from the past century or so.
Regarding the “Mary” with the disciples; throughout the 4 Gospels, Matthew, Mark, Luke, and John state that there were others, in addition to the 12, who traveled with Jesus. Take for instance when Jesus sent out the 70 or 72 apostles in pairs to spread His message. Where would those additional 58/60 have come from and known His message if they had not also traveled with him. I see the “Mary” as representing these who are mentioned but often ignored as we center, as Jesus did, on the training of the 12. (of course it didn’t quite take with Judas Iscariot)
