45 We also wish at this point to pay the highest tribute of praise to the care taken of the sick, the infirm and affflicted of every kind; We mean hospitals, leprosaria, dispensaries and homes for the aged and for maternity cases, and orphanages. These are to Our eyes the fairest flowers of missionary endeavor; they give us as it were a vision of the Divine Redeemer Himself, who "went about doing good, and healing all that were oppressed."
