"The word dogma comes from the Greek verb dokein, to seem to be, to appear to be. A dogma, therefore, was something which appeared to be a truth: an opinion about truth, and hence was frequently employed in certain Greek states as signifying the decision, the considered opinion, and therefore the final vote arrived at in a state council or assembly. It was only in later times that the word dogma acquired the meaning which it now has: a doctrine based upon the declaration of an ecumenical council, or perhaps of some other widely recognized churchly authority."
