PARSONS: Yes.
CARTER: We give a resounding yes.
PARSONS: If R.C. were here, he would say that “fully God and fully man” is not the best phrasing. Instead, we would prefer to use the more accurate creedal language, “truly God, truly man”—vera Deus, vera homo. So when we speak of Jesus Christ, while John might say “the Word was,” we can appropriately, in theological terms, speak of “Jesus who is.”
