92 Peace and joy! Yes, joy—because those who are really and effectively joined to the Mystical Body of Christ, which is the Catholic Church, share in that life which flows from the divine Head into each part of the Body. Through that life, those who faithfully obey all the precepts and demands of our Redeemer can enjoy even in this mortal life that happiness which is a foretaste and pledge of heaven's eternal happiness.
