The Gospel which the Church proposes to us on this Feast of the Most Holy Trinity describes an appearance of the Lord after His Resurrection. The Lord had given a precise order to His disciples: They are to meet at a specific mountain at a specific time. The Gospel tells us: “When they saw Him, they worshiped Him.” The disciples recognized Him as the Son of God, the Word of the Father, Creator of all things in Heaven and on Earth.

He proved that He was God by rising from the dead through His own power. That is why the Apostles – those who were to be witnesses to His Passion, His Death, and Resurrection – they lie prostrate before Him and adore Him.

The Lord affirmed His divine authority and power. He came to earth, sent by the Father, in order to reveal to us what He Himself is: the Word of God, the Son of the Father who was crucified and rejected by the men He came to save.

The Cross of Christ reveals the Loving Mystery of the Holy Trinity. St. Paul tells the Corinthians: “We preach Christ Crucified, a stumbling block to the Jews and folly to Gentiles.” It is through the Cross and in the Cross that the Trinity is revealed to the world in Jesus.

Today as we celebrate the Feast of the Holy Trinity – the Feast of the Mystery of God – the core mystery of our Faith, we are drawn again to the Cross. What we know about the Trinity comes from Jesus Who came to our world to share God’s life with us. Jesus proved that He was God be performing many miracles: He cured the sick, He gave sight to the blind, He cast out devils, He brought three people back to life. Jesus proved that He was God by going to the Cross for our redemption; He proved that He was God when He returned to life after His terrible death on the Cross.

After His Resurrection, when the Apostles were afraid and lonely, Jesus promised that He and the Father would not leave the Catholic Church which He established, alone and abandoned. He and the Father would send the Holy Spirit to be with the Apostles and with Church until the end of time.

Trinity Sunday is the celebration of the God who walks with us – who lives with us. The Trinity is the celebration of God reaching out to us in his love. The Trinity is the celebration of God choosing to show us that He is not a cold, lonely God – rather, he is God our Father, our Creator, our Sustainer, our Source of Life.

We can see His Majesty and power as we look at the world around us; and as we seek Him in the sacred scripture. We can come to discover that He wants a personal relationship with us, so He adopts us into his life of grace in the Sacrament of Baptism. The Trinity is the Celebration of God revealing Himself as Savior, in the person of Jesus Christ who took on flesh to be “Emmanuel” – God with us, and who suffered death on the cross to bring us back into a relationship with God our Father.

The Trinity is the celebration of the Holy Spirit who breathes God’s life into each of us and to all creation. When we are inspired, it is the Holy Spirit. When we live out the virtues of Faith, Hope, and Love – it is through the Holy Spirit. When we show the fruits of Love – Joy, Peace, Patience, Kindness, Generosity, Faithfulness, Gentleness or Self-Control – it is the Holy Spirit working through us and strengthening us.

On the day of our Baptism, water was poured on our heads in the name of the Father, and of the Son, and of the Holy Spirit, and we began to live a new life in union with the most blessed Trinity in the family of the Catholic Church. We live- out our spiritual lives by living in union with the Father and of the Son and of the Holy Spirit. The Trinity accompanies us on our journey of life – our journey to the house of our Father. St. Paul tells us: “we have our citizenship in heaven.” As the icon of the Trinity shows, the Trinity sits at the table of the Eucharist. But in the icon, there is a fourth place: that place is for us – we are drawn into the mystical presence of the Trinity through the Eucharist we are celebrating.

The mystery of the Most Blessed Trinity is the mystery of God reaching out to us in His love. In Jesus Christ, God the Father chose to show us That He is not a cold, lonely God sitting on a cloud in the heavens: rather, He is our Father who adopted us through the grace of the Sacrament of Baptism. He is our Savior who made Himself our Brother “Emmanuel” – God with us. He is Holy Spirit – our Helper and Guide – always with us.

On this Feast of the Holy Trinity, know that this Mystery tells us that God loves us; that we are not alone; and that He is the answer to the mystery of life and suffering and death.

May God Father, Son and Spirit fill us with life and hope.
