Proberbly, the most famous occultic religion is satanism, followed by wiccan. Many people belive the occult to be made up of just satanists and pagans, but as you will soon find out, there is a lot more: So, if you are a christian, of a jew, you could convert to the spiritual side of your religion, rather than converting to a completly new religion with totaly differant belifs. This would mean that you would hardly have to change your belifs at all, and there would be no tension when you go as a familly to your familly's religious place of worship. On the other hand, you may find that the belifs of another occultic religion make more sense. But remember, at the end of the day, you are the only one who can decide what you belive. Although you probably don't know it, but the world is practically ruled by occultism: Over a third of American presidents were (and still are today)*. Another famous occultist was Adolf Hitler; He wanted the state religion of Germany (and a Germanic empire) to be the original occultist religion that it was.
