“When the Pope uses the title of servus servorum Dei, originally assumed by Pope St. Gregory the Great as a description of the power of the Supreme Keys, one must remember that the formula servus servorum is not a genitive of object, as if the pope were the one who serves the servants of God, but an hebraic genitive signifying a superlative sense as in saecula saeculorum, virgo virginum, caeli caelorum, and so on.
