twin gods

Religion idea for my fantasy world. Y'know the one I'm always working on in the back of my head. All the gods are twins. Some are the same sex and some are brother/sister pairs. Representing the dual nature of the world. Life and Death, war and peace, day and night, y'know stuff like that. Now with that in place anyone who is a twin born into the world would most likely be drafted into the church. They would end up being priests, clerics, palladins, etc. Most of the time they wouldn't really have a choice as they would start their education in the clergy early on and their parents would support the idea because it gives them a step up in the social circles. Just another random thought.
