The Church is unwavering in upholding its dogmatic teachings, but does not insist upon those matters of faith which have not been specifically defined. The Eastern Orthodox believe that there must always be room for mystery when speaking of God. Individuals are permitted to hold "theologoumena" (private theological opinions) so long as they do not contradict traditional Eastern Orthodox teaching. Sometimes, various Holy Fathers may have contradictory opinions about a certain question, and where no consensus exists, the individual is free to follow his or her conscience.
