44 The holy Fathers, true witnesses of the divinely revealed doctrine, wonderfully understood what St. Paul the Apostle had quite clearly declared; namely, that the mystery of love was, as it were, both the foundation and the culmination of the Incarnation and the Redemption. For frequently and clearly we can read in their writings that Jesus Christ took a perfect human nature and our weak and perishable human body with the object of providing for our eternal salvation, and of revealing to us in the clearest possible manner that His infinite love for us could express itself in human terms.
