Much like The Walking Dead’s Father Gabriel, fans are introduced to Rabbi Jacob, who has lost all faith; though, we find out he continues to practice his religion and carry out rituals. 

Charlie stumbles upon the synagogue while scouting places that her group could make into a possible settlement and is taken in by the rabbi. While we’re first deceived into thinking Rabbi Jacob is very devoted to his religion, we soon learn he’s keeping his former congregation, who are all now undead, locked up in another area of the temple.
