Every year on the first Sunday after Pentecost, the Universal Church joyfully celebrates the Solemnity of the Most Holy Trinity.
The mystery of the Most Holy Trinity is central to our Christian faith and our Christian life, and this is why Holy Mother Church celebrates this special day in adoration of the Father, Son and Holy Spirit, the One God in three divine Persons. We entered the life with Christ through the sacrament of baptism in which we were baptized in the name of the Father, and of the Son, and of the Holy Spirit, baptized into the life of faith, hope, and love.
Love is one way of approaching the doctrine of the Holy Trinity since each Person of the Trinity is intimately bound to another in love. So great is this love that the Father and the Son and the Holy Spirit always remain as One divine nature, “adored in what is proper to each Person, their unity in substance, and their equality in majesty” (The Roman Missal, Third Edition) as is prayed in the Preface for the Holy Sacrifice of the Mass for today’s solemn day.
The Blessed Trinity is a communion of love, and everything that God does in moved by love. God the Eternal Father, who created heaven and earth and us out of love, sent his only Son into the world out of his great love for us so that we too might share in his love. God desires our love so much that he took the initiative and sent into the world his only Son who assumed our human nature by the power of the Holy Spirit.
The Son’s mission in the world was to make the love of God known to all and to reconcile the world back to the Father. Because of man’s sin, it was necessary for the Son to be sent into the world by the Father for the forgiveness of our sins, which was achieved by Christ’s Death and Resurrection. And before obediently offering his life on the cross, Christ promised the gift of the Holy Spirit who’s another Advocate for us as we live out our lives as faithful and grace-filled disciples in this world.
The sending of the Holy Spirit “who proceeds from the Father and the Son” is a gift which emanates from God’s love for us. The Holy Spirit will always guide us into the loving inner communion of the Trinity, and into heaven, where we’ll all share in this eternal and loving communion of the Father, Son and Holy Spirit.
