Solemnity of the Nativity of Our Lord


As I type this homily on November 10 for the celebration of the Solemnity of the Nativity of Our Lord on December 25, I am reminded of the Christmas Day sermon preached by Pope Leo the Great when he was Supreme Pontiff (Pope) between 440-461 A.D called “In Nativitate Domini.” Naturally the Holy Father was expounding on the two natures of Jesus Christ and the beauty, necessity and importance of the Incarnation (the Son taking on human flesh.) This was especially necessary in his time with so many heresies challenging the Scriptural and Traditional foundation of the Church’s teaching on Jesus Christ. 2000+ years later nothing has changed. Pope Leo was preaching about celebrating the Birth of Jesus Christ with great joy and exultation and that “there is no proper place for sadness,” because we keep the “birth of the Life, which destroys the fear of mortality and brings us the joy of promised eternity.” He says, “no one is kept from sharing in this happiness. There is for all one common measure of joy, because as Our Lord the destroyer of sin and death finds none free from charge, so He has come to free us all.” Pope St. Leo is saying that Jesus is the Savior of all. He reminds us of Christ’s victory and that the sinner is invited to pardon and to put off our old deeds and to take courage for we are called to Life. He wanted the people 1600 years ago and us today to know our fundamental Christian dignity and from whom we get it.

The Proclamation of the Birth of Jesus Christ is often proclaimed at the Midnight Mass because it shows that Jesus Christ is the summit of both sacred and secular history. It shows that all time is set by His Birth and by no other religious figure-He and He alone is THE Lord and Savior. All 4 sets of readings for Christmas point to St. Leo’s and St. John Paul II’s theme of the dignity of the human person and the importance and meaning of the Incarnation and how fundamental and necessary it is to “proclaim” this truth in private and public to the world, with trust and great rejoicing.

At the “Vigil Mass” Isaiah 62 shows we shall be called by a “new name pronounced by the mouth of God…and that we shall be a glorious crown in the hand of the Lord.” He wants to call us “espoused” and that the Lord “delights” in us, His crowning jewel of Creation. He goes on to say how God rejoices in us and that is why St Leo is saying: rejoice for this reason on Christmas Day! Psalm 89 states that we are God’s chosen ones and that we should be rejoicing in this knowledge of God’s everlasting and unconditional love for us. The Alleluia verse is a prophesy stating that “tomorrow the wickedness of the earth will be destroyed: the Savior of the world will reign over us.” It doesn’t say: the savior of Christians, but of ALL the world. Our subjective belief or disbelief doesn’t change the objective reality of the Truth of who He is.

At the “Midnight Mass” Isaiah 9 stresses that we should have abundant joy, be merry and have great rejoicing for what the “Wonder-Counselor, God-Hero, father-Forever, Prince of Peace has done for us. The Psalmist in Psalm 96 tells us that the earth should be rejoicing because our Savior is born. All this is rooted in the fact from whom and what Christ has redeemed us from: sin, Satan and eternal death. Since we are so dignified and God loves us so much and Jesus paid such a high price, a ransom for us St. Paul is telling Titus and us to “reject godless ways and worldly desires.” He has made us His own, so be “eager to do what is good.” The Church is always proclaiming this Good News of who God is and who we truly are as Christians. Pope St. Leo did this 1600 years ago as did Pope St. John Paul II did it for 27 years as pope especially in his “Theology of the Body” catechesis. Christmas isn’t just the celebration of Jesus’ “birthday,” that’s good for 2nd graders but for adults it is so much more than that. Proclaim from the rooftops the “good news of Great joy” – the Savior of the world is born.

At the “Mass at Dawn” Isaiah 62 reminds us of who we truly: “they shall be called a holy people.” Psalm 97 is all about rejoicing in this fact of who Jesus truly is, what he has done and IS doing for us now and who we are, His adopted children. The alleluia verse from the “Gloria” shows that doing the will of God will bring us true peace unless we fight against or do it begrudgingly. The Gospel of Luke shows that angels of God appear to the lowly and humble shepherds because they will be the most open to receive the message of God because they most reflect the Christ child Himself who is lowly and humble, we are to be the same. This indeed gives Glory to God in the Highest.

At the “Mass during the Day,” Isaiah 52 proclaims how beautiful for us to share our Catholic faith with others, not to be imposed upon them but sharing with them the Good News of Christ. Blessed are your feet that bring “glad tidings” to anyone announcing peace and salvation. Why not share it? Are you afraid of rejection, being ridiculed? Why worry or fear – “The Lord comforts His people.” Psalm 98 is all about singing and giving praise for the victory Christ has won on our behalf. In the great and powerful “prologue” of St. John it says: to those who did accept Him He gave power to become children of God.” Jesus did not redeem us just to purchase for us a “get out of jail free card.” He redeemed us, ransomed us, and freed us from Satan’s power, due to original sin, not for us to be enslaved in personal sin. But, that we become holy and truly great sons and daughters of the Father. Be glad and rejoice in the Birth of the Savior of the world. Have a Blessed Christmas Season, which doesn’t end until the Feast of the Baptism of the Lord. Amen.
