2) An authoritative principle, belief, or statement of ideas or opinion, especially one considered to be absolutely true. See Synonyms at doctrine.
3) A principle or belief or a group of them.
Usage: -- Dogma, Tenet. A tenet is that which is maintained as true with great firmness; as, the tenets of our holy religion. A dogma is that which is laid down with authority as indubitably true, especially a religious doctrine; as, the dogmas of the church. A tenet rests on its own intrinsic merits or demerits; a dogma rests on authority regarded as competent to decide and determine. Dogma has in our language acquired, to some extent, a repulsive sense, from its carrying with it the idea of undue authority or assumption. This is more fully the case with its derivatives dogmatical and dogmatism.
