How old is this expression in the Byzantine rite? Is there a danger of understanding the kingship of Christ, as used in the Byzantine tradition, by referring to the human analogate as primary, rather than the Divine analogate? (As there may be such a danger in the Roman rite, especially with the Feast of Christ the King? See the comments of Fr. Bouyer in Liturgical Piety.) The Word is to rule in our lives, by ordering our actions and infusing us with Divine Love -- and human kingship is to be in accord with this.
