The Son, which is the Word of the Father, begotten from everlasting of the Father, the very and eternal God, and of one substance with the Father, took man's nature in the womb of the blessed Virgin, of her substance: so that two whole and perfect natures, that is to say, the Godhead and Manhood, were joined together in one Person, never to be divided, whereof is one Christ, very God, and very man; who truly suffered, was crucified, dead and buried, to reconcile his Father to us, and to be a sacrifice, not only for original guilt, but also for actual sins of men. {325} But there are other points in the course of these important proceedings to which I would solicit your especial attention, with the view of comparing the sentiments of the Bishop of Rome at that day, and also the expressions employed by other Chief Pastors of Christ's flock, with the language of the appointed authorized services of the Roman Church now, and the sentiments of her reigning Pontiff, and of his accredited ministers. The circumstances of the Church Catholic, as represented in Leo's letter in the fifth century, and the circumstances of the Church of Rome, as lamented by the present Pope in 1832[124], are in many respects very similar. The end desired by Leo and Flavianus, his brother pastor and contemporary, Bishop of Constantinople, and by Gregory, now Bishop of Rome, is one and the same, namely, the suppression of heresy, the prevalence of the truth, and the unity of the Christian Church. But how widely and how strikingly different are the foundations on which they respectively build their hopes for the attainment of that end! [Footnote 124: "The encyclical letter of our most holy Father, Pope Gregory, by divine providence, the sixteenth of that name, to all patriarchs, primates, archbishops, and bishops."] The present Roman Pontiff's hopes, and desires, and exhortations are thus expressed[125]:-- [Footnote 125: This is the translation circulated in the Roman Catholic Annual, p. 15, called, The Laity's Directory for the year 1833; on the title page of which is this notice: "The Directory for the Church Service, printed by Messrs.
