If you remember that Jesus Christ is God, that He had the power to make this change, that He could confer this power on others, as the apostles and their successors, that He did so when He said: "Do this in commemoration of Me," and that this change at the present time as at the time of the apostles is made by His almighty power, you will have no difficulty in believing it. The belief and practice of the Catholic Church of to-day regarding the Blessed Sacrament is the same as it was in every age since the time of Christ. The history of every century tells us this. The Fathers, Doctors, and Church writers of every age say the same. If it were not so, some one ought to be able to find the time when the doctrine was invented, and the person who invented it. But, since no one has been able to find the inventor of this doctrine and practice, the time or place of the invention, we rightly conclude that they came down to us from the time of Christ, and had Christ for an author. (Berengarius, in the eleventh century, was the first who denied this doctrine.) If, then, Christ is the author, is not the Catholic practice reasonable? But I don't understand the Catholic doctrine regarding the Blessed Sacrament, some one may say; therefore it is contrary to reason. Dear reader, did the consummate puerility, silliness, foolishness of such an objection ever present itself to you? Do you understand the Blessed Trinity? And is it contrary to reason? No. Although above reason, it is not against it. Do you understand how Jesus Christ is both God and man? Do you understand any mystery? No. If you did it would no longer be a mystery. For a mystery is something above human intelligence. It is something incomprehensible to us, for it pertains to the divine intelligence. And as well might you attempt to pour the mighty ocean into a small hole on the shore, as attempt to hold with your limited capacity the illimitable ocean of divinity. The proper office of reason is to examine the evidences of revelation, and see if God has spoken. But it constitutes no part of its office to dispute the word of God. That God has spoken is evident from the fulfilment of many prophecies and the authority of many miracles. That these prophecies have been fulfilled, and these miracles performed, is as certain as is any historical fact. Reason teaches us this. It teaches us, too, that no one but God (or by the power of God) can prophesy; no one but God can derogate from the order of nature, by the performance of a miracle. Reason teaches us, then, that God has spoken. When we know God speaks, genuine reason will dictate that we humbly believe His holy word. Thus will true reason ever act. And when God says, "This is My body," it will not hesitate to believe.
