I think that maybe the biggest problem with us is that by repeating things, they become routine. This applies to everything: work, school, play, the company we keep, pastimes we enjoy, prayer, worship, and on and on. Allow me to point out a few moments in Scripture before we truly begin:
When the angel visited the Virgin Mary and announced to her Whose mother she would be, she said, “Let it be so” (Lk. 1:38), and at that moment, the Holy Spirit came down and formed, in her virgin womb, the human nature of God’s eternal Son. John the Baptist found such joy in the presence of the incarnate Lord and His Blessed Mother that he leapt for joy in the womb of Elizabeth, while she herself was moved to say, “How does this happen, that the Mother of my Lord should come to me?” (Lk. 1:41, 43). Then, when Our Lord was born, all the angels appeared and acclaimed, “Glory to God in the highest” (Lk. 2:14). When Simeon saw the Child Jesus, he considered his life finished at last and said with complete contentment, “Now you may dismiss your servant” (Lk. 2:29).
Much later in the life of Christ, in the 14th chapter of St. John’s Gospel, Our Lord is speaking to the Apostles about the place He is going to after His resurrection. Philip, in all sincerity, blurts out, “Lord, show us the Father, and it will be enough for us” (Jn. 14:8). There is a certain frustration in Our Lord’s response: “Have I been with you so long, yet you have not come to know Me, Philip? He who has seen Me has seen the Father. Do you not know that I am in the Father and the Father is in Me?” (Jn. 14:9-10).
Why do I mention all this? Because of the privilege which we have even today, which can be so often forgotten about due to the routine nature of our lives. When Our Lady said, “Let it be done to me according to your word” and Our Lord was made flesh in her womb, God became tangible. He became something we could see, touch, speak to, and hear, with the senses. In His new nature He became limited also, not losing but voluntarily placing aside the Divine Majesty so as to live like us and, ultimately, redeem us to the Father. The Lord, who until now had been infinitely distant, became intimately close. And this brought immense joy to all those who recognized what had happened: to Elizabeth, to John the Baptist, to Simeon, and to the whole Host of Heaven. Our Lord wanted Philip to recognize that He, Jesus Christ, is truly Emmanuel, “God with us”.
So now comes the important part: Do you, my fellow Catholics, recognize that the very same miracle which occurred in the womb of the Blessed Mother happens at every Consecration in the Mass? When Our Blessed Lady said to the angel, “Let it be done to me”, the Lord was made present there, physically, where He had not been so before, and all of Heaven was “concentrated” into Our Lady’s womb. The same thing happens in the Mass. When the priest repeats the words of Our Lord, “This is My Body . . . this is My Blood”, the Host and the wine are changed into Christ, and so, as at His conception, He is made physically present where He was not before, and all of Heaven is concentrated into what once was bread and wine on the altar.
It can be so difficult to remember this when we go to Mass, Sunday after Sunday, with our off-key choirs and boring homilies and unedifying church buildings and whatever else. But it is the reality of what happens in the Mass. Whether it is a Mass where the red is perfectly and reverentially adhered to and the black is perfectly and reverentially said, or a Mass where the priest makes up half the prayers and tries to be the center of attention, it is still the reality of the Mass (provided the correct words and matter are used, the correct intention had on the part of the priest, and the priest validly ordained, of course): God the Son, and in fact the entire Trinity due to the union of the Divine Nature, comes down to us in our own church and lifts us up to the sphere where, even now, He is “as a Lamb slain from the foundation of the world” (Rev. 13:8). The only difference between Heaven itself and the Holy Sacrifice of the Mass is that in Heaven, we will see Almighty God, Father, Son, and Holy Spirit, as He is, while here we see Him only veiled, and in Heaven there will be no more barrier of sin to separate us from sharing in His life.
Fr. Calvin Goodwin, FSSP, said the following concerning the Mass: “…at the moment of Consecration, it’s not so much that Christ merely comes down, but that He lifts us all to the sphere where He lives in glory, once again beyond time and the limitations of this world, to the very presence of God” (qtd here, “Roman Catholic Mass Explained”). The Mass itself says, before the Sanctus, that we sing of God’s holiness together with the hosts and choirs of Heaven. The Holy Mass is not just the worshipping act of your or my particular parish, it is the act of the entire Church, both in Heaven and on Earth, a unitive act where you might say that Heaven and Earth are temporarily joined together. So in a certain sense those who say Heaven is a place on Earth are correct: they need look no farther than the Holy Sacrifice of the Mass.
