Contrary to, or differing from, some acknowledged standard, as the Bible, the creed of a church, the decree of a council, and the like; not orthodox; heretical; -- said of opinions, doctrines, books, etc., esp. upon theological subjects.
(HET·er·o·DOX). Holding beliefs or opinions contrary to right teaching. Generally applied in a church doctrine context to people not in agreement with the accepted beliefs of Orthodox Christianity. In the gentile Greco-Roman Christianity of the fourth century Judeo-Christians were rejected as heterodox as they continued with Sabbath observance and observing the Christian Passover on Nisan 14. Judeo-Christians, in kind, saw the Greco-Roman Christians as no more than Christianized pagans.
