Talking God in the office might be boring but it hardly counts as a sacking offence
Fortunately, it's not a sacking offence to be the office bore, even if droning on about your pet subject irritates colleagues. Otherwise, a great many sports fans would be shown the door. Out of work, too, would be fitness-fixated people who insist on sharing every detail of their gym regime. Obsessive calorie-counters would be gone, not to mention parents and dog-owners who expect everyone to share their infatuation.
