I have mixed feelings about the work of Jake Stratton-Kent, but he’s right about one thing. Goetia is the continuation of the spirit centered practice in the West. You don’t need to go appropriating cultures. While the African traditions can fill in the gaps of the knowledge we have lost, there are perfectly viable spirit and ancestor traditions in many European cultures. Do your research. Follow your bloodline. If necessary, St. Cyprian is a fall back.
