Too much time is often spent on arguments which - even if they are proved-do not attract to the Church. The aim in all discussions should be to make those outside the Church catch a glimpse of the treasures which are within. There is no more effective way of doing this than by the presentation of the doctrine of the Eucharist.
     Even those who know Jesus dimly and uncomprehendingly are lost in admiration of him. On the strength of human evidence they acknowledge that he exercised an unexampled power over nature, so that the elements obeyed him; the dead returned to life; and infirmities fled at his command. He did all these things directly of his own power, because, though man, he was likewise the Eternal God himself, who made all things, whose word is might.
     The Scriptures tell how once that God-man - among innumerable other wonders - accomplished the sweet miracle of the Eucharist. "Jesus took bread, and blessed, and broke it, and gave it to the disciples and said 'Take, eat; this is my body'." (Mt 26:26) This is a mighty scripture, but for how many has it not been a sealed one? "This teaching is difficult; who can accept it?" (Jn 6:60) The objection of some even of his own disciples has echoed down through the centuries to the infinite loss of souls: "How can this man give us his flesh to eat?" (Jn 6:52) Those disciples could almost be pardoned for their  unbelief, for they had not grasped the real nature of him who stood in their midst. But what is it that clouds the minds of those persons who acknowledge the Divinity and hence the omnipotence of Christ? Surely these should see how deceptive - how unthinkable therefore - it would be for that same Divine Person -- when solemnly addressing simple folk - to say "My Body," while meaning "not My Body." Let them absorb the ruthless logic of Pascal: "How I detest this folly of not believing in the Eucharist. If the gospel is true; if Jesus Christ is God; where is the difficulty in the matter?"
     The challenge of so overwhelming an idea as the Eucharist cannot be heard unheeding. To hold up persistently to the notice of those who are not Catholics this crowning glory of the Church must force their minds to contemplate its possibility; so that many will reason to themselves: "If this is true, how dreadful is my present loss!" In the pang of that thought will come the first big impulse towards their true home.
     Many earnest persons outside the Church read the Scriptures, and in meditation and sincere prayer seek to draw Jesus out from the dim past of history, rejoicing if their imagination creates a vivid picture of their Lord engaged in his works of love. O! if these souls could only understand that in the Church there is the wonder of the Eucharist, which could bring Jesus as he is, whole and entire, in all his physical reality, with all his Divinity, into the sphere of their present lives! If they could realize that by this means they could touch him, talk to him, contemplate him, or busy themselves about him more closely, more intimately by far than did his dear friends at Bethany! Nay more! by Holy Communion in union with Mary they could render to that Divine Body all the loving cares of a Mother, and thus, in some sense, thank him adequately for all that he has done for them. Surely the unsurpassable good of the Eucharist has only to be explained to multitudes outside the Church to cause them to yearn for light. Then Jesus will give them understanding of the things that are concerning him. Like the disciples journeying to Emmaus, their hearts will burn within them as he speaks on the way and opens to them the sense of that "hard saying" of his: "Take, eat; this is My Body." (Mt 26:26) And their eyes will be opened, and they will know him in the breaking of the Bread Divine. (Lk 24:13-35)
     In this recognition of the Eucharist, the misconceptions and prejudices which chilled the understanding and darkened the view of heaven, melt away like snowflakes in a burning sun, so that he who had walked unseeing will exclaim with overflowing heart: "One thing I do know, that though I was blind, now I see." (Jn 9:25)
 
     "Our Lady of the Blessed Sacrament is Mary receiving in her capacity as universal dispenser of grace the full and absolute disposal of the Eucharist and of the graces which it comprises. For this Sacrament is the most efficacious means of salvation, the most excellent fruit of the redemption brought by Jesus Christ. Consequently it is for her to make Jesus known and loved in this Sacrament. It is for her to spread the Eucharist all over the world, to multiply churches and to plant them among infidel peoples, to defend the belief in the Eucharist against heretics and the impious. It is her work to prepare souls for Communion, to move them to visit frequently the Blessed Sacrament and watch constantly before it. Mary is the treasury of all the graces which the Eucharist contains, of all which lead to it, of all which flow from it." (Tesnière: Mois de Notre-Dame du T. S. Sacrement)
