mary, joseph, and joseph of arimathea were arimatheans from the british isles who settled in galilee. they were mostly a red-haired people.
joseph of arimathea is known in the bible for paying for jesus' funeral. he was also a wealthy tin baron whose tin mines were in cornwall. the stuff about his mines in cornwall can be found on his wikipedia page. he was mary's brother and jesus' uncle

after jesus was killed, resurrected, and then ascended back to god the father, roman jews couldn't just kill mary and the disciples because that would have just made them martyrs; so they put them all in a ship, broke off all oars, sails, and rudders, and then they left them there in the middle of the mediterranean sea
>if jesus is for real, then surely you'll get out of this pickle!
god, they were so retarded even back then. the ship drifted for a few days and landed in france, in saintes-maries-de-la-mer, where the locals helped repair their ship so they could sail back to cornwall where joseph of arimathea was. to this day, that town still holds yearly celebrations for their arrival

they met back in cornwall with josepth of arimathea. a little later, they gathered in glastonbury and formed the first church there in 37 AD. after the formation of the church, the disciples decided to spread throughout the earth.
upon hearing that the disciples had survived, roman jews launched a massive campaign in the british isles in 42 AD

then in 325 AD, constantine and the roman jews formed their own bible and christianity was suddenly OK in rome again
