a term "practically limited to belief in something that is contrary to the decision of some church or churches; thus, when a Romanist or a Lutheran, etc., speaks of heterodoxy, he means something in opposition to the teaching, respectively, of the Romish or Lutheran Church, etc., so that what is, or at least is understood by heterodox, at one time or place, will be orthodox in another. See Martensen, Dogmatics 28. (See HERESY); (See ORTHODOX).
