Although technically a "religious" show, the majority of the episodes in the series had no religious themes in them. In fact only 1/3 of the episodes actually had religious (Christian or Catholic) themes to them. Also the majority of the episodes in the series have mild swearing ("damn" and "hell") meaning that the show really wasn't Christian or Catholic based.
The series was produced in the United States, and nearly all of its episodes were set there, but the animated opening credits show cars driving on the left-hand side of the road.
