Each year on the first Sunday after Pentecost we celebrate the Solemnity of the Most Holy Trinity, also known as Trinity Sunday. Although it wasn’t until 1334 that Pope John XXII officially established the feast for universal observance in the Western Church, the mystery of the Holy Trinity has been the pulse of the Church’s life since the very beginning. The Trinity is “the central mystery of Christian faith and life…[and is] the source of all the other mysteries of faith” (CCC 234). The whole of the Church’s life flows from the central belief that the one true God exists as three divine Persons—Father, Son, and Holy Spirit. Since the very beginning of time, God has gradually revealed and communicated the truth of who he is as Trinitarian through what he has done in salvation history (see CCC 53-67). Although God gradually revealed himself throughout different stages of the Old Testament period of salvation history, mankind had no way of knowing the full truth of God’s inner life of the Trinity before the time of Christ, since this mystery of our faith is “inaccessible to human reason alone…before the Incarnation of God’s Son and the sending of the Holy Spirit” (CCC 237).
In his encyclical Spe Salvi, Pope Benedict XVI poses a challenging question: “So now we must ask explicitly: is the Christian faith also for us today a life-changing and life-sustaining hope…which shapes our life in a new way, or is it just ‘information’” (Spe Salvi 10) that doesn’t change us? Furthermore, what difference does this central mystery of our faith make in our daily lives?
Trinity Sunday is an invitation to remember that “[being] Christian is not the result of an ethical choice or a lofty idea, but the encounter with an event, a person, which gives life a new horizon and a decisive direction” (Deus Caritas Est 1). In revealing himself as Trinitarian, God hasn’t merely shared impersonal facts about himself; rather, God has shared himself with us, and has invited us into his own inner life and communion of love, which alone is the origin, goal, and meaning of our life. As we read in the Catechism, “By sending his only Son and the Spirit of Love in the fullness of time, God has revealed his innermost secret: God himself is an eternal exchange of love, Father, Son and Holy Spirit, and he has destined us to share in that exchange” (CCC 221). On Trinity Sunday, the Church proclaims the truth about God—that God is love (1 John 4:8)—and the truth about us: we are made for this love. We eternally belong to God—we have an eternal home!
St. Elizabeth of the Trinity leads us more deeply into this reality by saying that “The Trinity—this is our dwelling, our ‘home,’ the Father’s house that we must never leave.” When speaking with his disciples before his Passion, Jesus directed the gaze of their hearts towards this truth: “In my Father’s house there are many rooms…and when I go and prepare a place for you, I will come again and will take you to myself, that where I am you may be also” (John 14:2-3). Jesus continued to reveal more of the Father’s loving plan: “I will not leave you orphans; I will come to you…If a man loves me, he will keep my word, and my Father will love him, and we will come to him and make our home with him” (John 14:18, 23). Jesus reveals to his disciples the Father’s breathtaking desire. He desires not only that we be at home in him when we get to heaven in the future, but he desires us to be at home in him now—and so, he comes to us, he makes his home among us (c.f., John 1:14) in order to make his home in us. Thus, with the Feast of Pentecost and the sending of the Holy Spirit, God fulfills his promise to never leave us orphans. This is why the Church celebrates Trinity Sunday the week after Pentecost: On Pentecost, “the Holy Trinity is fully revealed” (CCC 732).
“I will not leave you orphans!” If Jesus has promised to never leave us orphans, then that means we have a permanent home—we eternally belong to the Father as children of his heavenly household! This is the mystery into which the Church invites us more deeply on the Solemnity of the Most Holy Trinity. Yet this truth is also the very gift that that we are invited to share with all whom God entrusts to us in our daily lives: “Love one another as I have loved you” (John 15:12). Every human heart longs for its eternal home. Today, we invite the Trinity to be more at home in our hearts in order to make them a more welcoming home for others—that through our smile, our gentleness, our availability of heart, everyone whom the Father entrusts to us may experience the Love that is their eternal home.
Question for Reflection: Today, will we allow our hearts to be touched and changed by the reality into which Trinity Sunday invites us more deeply?
I still remember as if it were yesterday. There I was—a junior in high school with my sights set on my then life’s goal of playing college soccer—listening to the doctor tell me the results of the recent X-ray: “You have a stress fracture in your left ankle.” My heart sank, and I immediately focused on the most apparent, inevitable consequence of that injury: I would have to sit out the whole season, meaning I would miss crucial recruiting opportunities. To say the least, I was discouraged as I stood before the rather large and ominous mountain that so suddenly impeded the pursuit of my goal. I instantly began feeling sorry for myself and let anger creep into my heart. Then, in what I now look back upon and gratefully remember as “the moment of mercy,” I heard God’s gentle voice speak to the depths of my heart and tell me, “Carolyn, there’s more to life than soccer.” With my heart pierced by that voice, my desire to play college soccer disappeared. I soon began making decisions that would lead me to the people and places that God had in mind for me to more deeply encounter His mercy and to discover the actual goal of my life.
During my first year of college, the Lord sent a spiritual director into my life who asked me a life-changing question: “Carolyn, what is the goal of your life?” At that time, I couldn’t honestly answer, since I couldn’t yet put into words what the Lord had begun stirring in my heart through the stress fracture event. Yet, over the next few years of college as I continued spiritual direction and developed a more habitual prayer and sacramental life, the Lord began to show me the answer to the question: Communion with God—holiness—is the goal of my life, because Love is the meaning of life.
In a special way during this Jubilee Year of Mercy, the Church is called to be “a living sign of the Father’s love in the world” (Misericordiae Vultus 4). At the heart of the Jubilee Year of Mercy, we find the Person of God the Father, whose love is both the origin and goal of our life. The Year of Mercy is a special time of grace in the Church, and Jesus invites us to daily re-encounter our Heavenly Father, to be renewed by His love—which alone gives meaning to our life—and to joyfully share the gift of His love with those whom the Lord entrusts to us each day. At a General Audience on December 9, 2015 (the day after the opening of the Year of Mercy), Pope Francis emphasized the purpose of the Jubilee Year:
Turning our gaze to God, our merciful Father, and to our brothers and sisters in need of mercy, means focusing our attention on the essential contents of the Gospel: Jesus, Mercy made flesh, who renders the great mystery of the Trinitary Love of God visible to our eyes. Celebrating a Jubilee of Mercy is equivalent to placing once again the specific nature of the Christian faith, namely Jesus Christ, the merciful God, at the center of our personal life and that of our communities.
In other words, Pope Francis is saying that the invitation during this Jubilee Year of Mercy is to “return to the basics” of our faith: to enter more deeply into the mystery of the Holy Trinity, which is “the central mystery of Christian faith and life” (CCC 234). In fact, Pope Francis begins his letter for the Jubilee Year with words which aim to “sum up the mystery of the Christian faith”, namely, that “Jesus Christ is the face of the Father’s mercy” (Misericordiae Vultus 1). Jesus’ whole earthly mission was to reveal the truth about God’s inner life of love and man’s vocation to that love that originates from the Father’s heart (John 17:3; CCC 514-518). This is why Jesus tells Philip, “He who has seen me has seen the Father” (John 14:9). Everything Jesus says and does reveals the Father (CCC 516) and aims at “restoring fallen man to his original vocation” (CCC 518) of love.
Thus, the Jubilee Year of Mercy is a special moment of grace to daily re-orient the gaze of our hearts towards the merciful gaze of the Father that tenderly awaits us. This gentle and loving gaze of the Father reveals the love that alone is the origin, goal, and meaning of our life. As Pope Saint John Paul II says, “Man and man’s lofty calling are revealed in Christ through the revelation of the mystery of the Father and His love” (Dives in misericordia 1). May we live this Jubilee Year by creating the space in our daily lives—particularly through prayer and frequent reception of the Sacraments—to encounter Jesus and to let our merciful Father love us. We ask Mary, Mother of Mercy, to help us open our hearts and be more receptive to the Father’s love. May we give her permission to use us as instruments of God’s mercy in the lives of others so that we can share the gift of His love with those whom God entrusts to us.
