Heterodoxy is simply the affirmation of a teaching or belief that differs from the "orthodox" norm. However, orthodoxy may not always be a good thing, if the norm itself is not absolutely true. From a Unificationist perspective, heterodoxy is therefore a neutral concept. Whether it is right or wrong to affirm heterodox beliefs depends on whether orthodox beliefs happen to be true or false.
In God's providence, the champions of God often held heterodox views in comparison to the prevailing cultural norm. Abraham left the polytheistic world of Mesopotamia to follow God's call to go to Canaan, where he established a heterodox monotheisitc tradition at a time when the Canaanites, too, held polytheistic beliefs. Moses denied the prevailing orthodoxy of the Egyptian religion in which he had been raised for 40 years in Pharaoh's palace. He confronted the Egyptian king with a heterodox belief in the Hebrew God Yahweh, on whose behalf he demanded: "let my people go." Jesus, in teaching his disciples that he was the Messiah, expressed a heterodox belief according to the majority of Jews of this day. Saint Paul's views on the circumcision of Gentiles were seen as heterodox by many Jewish Christians. Saint Francis of Assisi taught views on ecclesiastical poverty that some churchmen considered heterodox. Martin Luther's views on papal indulgences were considered heterodox as well.
In the final analysis, it is one's conscience that determines whether it is right or wrong to express heterodox views. According to the Reverend Sun Myung Moon:
God has given you a conscience as your guide... Your conscience knows everything about you. It has complete knowledge of every action and step you take; it even knows your thoughts. Your conscience knows all these things about you before your teacher or your pastor knows. It knows them before your parents know. It knows them even better than God knows.
