Christ, the head of the Church, having been glorified, it remains that his body, the people of God, who are his peculiar inheritance, he having acquired it with his blood, should be equally glorified. Christ then says to his Father, or the Prophet says to Christ, "Save thy people," and, in order to save them, "Bless them," by justifying them; "Rule them," by shielding, by protecting them on the road; "Exalt" them, by glorifying them, by glorifying them to eternity.
