134 Nor is it to be admitted that by this Eucharistic cult men falsely confound the historical Christ, as they say, who once lived on earth, with the Christ who is present in the august Sacrament of the altar, and who reigns glorious and triumphant in heaven and bestows supernatural favors. On the contrary, it can be claimed that by this devotion the faithful bear witness to and solemnly avow the faith of the Church that the Word of God is identical with the Son of the Virgin Mary, who suffered on the cross, who is present in a hidden manner in the Eucharist and who reigns upon His heavenly throne. Thus, St. John Chrysostom states: "When you see It [the Body of Christ] exposed, say to yourself: Thanks to this body, I am no longer dust and ashes, I am no more a captive but a freeman: hence I hope to obtain heaven and the good things that are there in store for me, eternal life, the heritage of the angels, companionship with Christ; death has not destroyed this body which was pierced by nails and scourged, . . . this is that body which was once covered with blood, pierced by a lance, from which issued saving fountains upon the world, one of blood and the other of water. . . This body He gave to us to keep and eat, as a mark of His intense love."
