2 In truth, Christ our Lord, setting Himself to fulfill the commandment which His Father had given Him, straightway imparted a new form and fresh beauty to all things, taking away the effects of their time-worn age. For He healed the wounds which the sin of our first father had inflicted on the human race; He brought all men, by nature children of wrath, into favor with God; He led to the light of truth men wearied out by longstanding errors; He renewed to every virtue those who were weakened by lawlessness of every kind; and, giving them again an inheritance of neverending bliss, He added a sure hope that their mor tal and perishable bodies should one day be partakers of immortality and of the glory of heaven. In order that these unparalleled benefits might last as long as men should be found on earth, He entrusted to His Church the continuance of His work; and, looking to future times, He commanded her to set in order whatever might have become deranged in human society, and to restore whatever might have fallen into ruin.
