Nicholas Patrick Cardinal Wiseman very ably proves that the Bible proves the real presence of our Lord Jesus Christ in the Most Blessed Eucharist and in the Holy Sacrifice of the Mass. He begins by presenting the Catholic doctrine as well as the beliefs of the other Christian Churches. He then proceeds to the proof from various portions of Sacred Scripture, such as chapter six of Saint John's Gospel and he words of institution of Jesus, Himself. He then demonstrates how the Protestant interpretation does not fit the clear meaning of the Bible. He closes with a discussion of the Catholic doctrine of transubstantiation.
