I wouldn't be surprised if it includes some gory detail on his marriage to Mary. According to Catholic tradition, Mary was perpetually a virgin, meaning that Joseph had never had sex with her. That is why some Catholics call a celibate marriage a Josephite marriage.Or there is actually a whole discipline in Catholic theology called "Josephology." Look it up, I'm not making it up. There are whole tracts and studies into Joseph, the husband of Mary, and his role in universal salvation. And he isn't even mentioned in more than a handful of verses total as doing not much more than being just the guy who married Marry.
Another thing fun. There was once a monk named Jovinian (died 405 CE) who decided that marriage was as blessed as celibacy. His opinion was declared a heresy by the Church.
Yep. There's a lot to be said for that.I keep comparing theology with Fan Dumb, but yeah, for that reason. If someone spent many years and wrote many pages arguing the role of Captain Pike in saving the galaxy, in the original Star Trek series, via his influence of Spock and Kirk, even most die-hard trekkies would think it's not healthy to be that (A) obsessed and (B) into taking one's own ass-pulls as reality. But you do that for Joseph, they call you Pope John Paul II.
One finds the same sorts of disputes as to what is canonical and what is not, and one finds some similar analysis techniques.
A notable one is the retcon, short for retroactive continuity. Serial works often end up with lots of continuity problems and outright contradictions, and some fans have created various retcons to reconcile them. Sometimes the creators of the works themselves create retcons, like Pam Ewing dreaming an entire seasons of Dallas. Some notable theological arguments qualify as retcons, like Genesis 1 vs. Genesis 2 creation, Matthew vs. Luke genealogy, etc. Islam has the retcon that previous prophets were proto-Muslims whose teachings got mangled by their followers.
