It is well-known among Orthodox Christians that the word orthodoxy—often used as a shorthand for our faith—has two parallel meanings. It is composed of two Greek words—orthos and doxa. Together, they form orthodoxia, rendered into English as orthodoxy. The word orthos literally means “straight,” and those familiar with geometry will recognize it in the word orthogonal, which refers to something lying at a right angle. Those who know something about dentistry will think of orthodontics, which concerns itself with straight teeth, while the orthopedist wants to make sure your skeleton is straight (literally, orthopedics means “straight children”). It should come as no surprise that Greek uses orthos metaphorically also to refer to something that is true, since we English speakers use straight to refer to reliability and truth, especially in such terms as straight-talker or to be set straight. And of course someone who is on the right path is on the straight and narrow. And no doubt our minds are also called to the use of the word straight to refer to a properly ordered sexuality or even from a decade or two ago when straight referred to someone doesn’t take recreational drugs.
The other side of the word orthodoxy is what may intrigue us more, however, and it is the doxa which gives orthodoxia its double meaning, for doxa can mean both “opinion” and “glory.” Often, in thinking of orthodoxy, it is this first meaning that occurs to the world—an “orthodoxy” is a hard and fast, unmovable set of teachings or opinions. And this meaning should occur to us, as well, that Orthodoxy is very much about the straight, true teachings of the Church, teachings that cannot be changed. The orthodoxy of the Orthodox Church is therefore precisely a deposit of faith, a theology that will never be altered, because it is the truth. It is the straight teaching, the true opinion.
