It seems more common, and more necessary, to modify most Protestants with one or more adjectives. For example, it is not uncommon to modify the word "Episcopal" with the words "high" or "low" or "broad" or "conservative" or some such. Likewise, it is not uncommon to modify the word "Lutheran" with "liturgical" or "confessional" or "conservative"--or the corresponding pejoratives. The same is true of (and in) many other Protestant denominations.
To be sure, there are adjectival Orthodox. However, the adjectives generally denote ethnicity (Russian, Serbian, Greek) or rite (Byzantine or Western). One rarely, if ever, modifies Orthodox with "liturgical" or "conservative." To say it another way, the adjectives do not modify the distance one is perceived to be from his own tradition or from the Fidei Depositum.
Why this observation? It was prompted by my need to modify the word "Lutheran" in the previous brief obituary; and because, now that the school year is winding down and the teaching load lessening, I have occasion to think and write about such things.
