Professor Julia Kapatelis is explicitly described in comics as having been born to and raised by Greek Orthodox parents.
Julia Kapatelis has an additional spiritual heritage rooted in Greco-Roman classical religion from the time she was rescued by Amazons, taken to Themyscira, and implanted with subliminal desires to teach Amazonian ideals of peace. Julia Kapatelis is regarded by Amazons as a spiritual sister, although she is not Julia Amazonian by birth.
