Jesus and Mo share a flat (and a bed), and occasionally venture outside, principally to a public house, "The Cock and Bull", where they drink Guinness and engage in conversation and debate with an atheist female bartender known simply as Barmaid, who is never drawn but is characterised only as an out-of-frame speech bubble. The barmaid functions as the voice of reason when criticising the Abrahamic religions or religion in general. Other times, Jesus or Mo may act as the voice of reason depending on which religion a particular comic aims to criticise. Jesus will act as the author's mouthpiece if the comic aims to criticise Islam while the character Mo will be used to criticise Christianity. They also converse with each other on a park bench.
