 Gregory of Nazianzus' description of this cult occurs in his eulogy for his father, who was a Hypsistarian before his conversion to Christianity.This cult may have formed as the native Cappadocian cult of Zeus Sabazios integrated with the cult of Jahve Sabaoth practiced by the numerous and intellectually predominant Jewish colonies, and that associations ("sodalicia, thiasoi") of strict monotheists formed, who fraternized with the Jews, but who considered themselves free from the Law of Moses.A late 3rd century CE shrine in a wall of the ancient city of Oenoanda provides the strongest archaeological evidence for this cult.
