Last Sunday we celebrated the solemnity of Pentecost and the gift of the Holy Spirit bestowed upon the Church which concluded our celebration of the Easter season. Now in the liturgy we are back in ordinary time. As every year, the first Sunday that comes after Pentecost is the Holy Trinity Sunday. It invites us to meditate on the central mystery of our faith, namely, God as a communion of love: Father, Son and Holy Spirit. It looks like that there is nothing more distant from our human experience and nothing more abstract for our minds, that this truth of our faith. And yet, as Christians we are not only deeply immersed into this mystery, in the end the sharing in the life of the Trinity is the deepest longing of our hearts.
In common opinion, the Trinity Sunday is a nightmare for preachers. How can you preach on something so remote from us and on something that we will never be able to grasp. In the past, there have been several attempts to explain at least partially this mystery by some theologians and all of them failed. However, I enjoy speaking on this topic. Not because I understand more than others, I don’t, but because of a certain paradox of our faith. As profound, mysterious and complex this truth is, it is at the same time very simple. The doctrine of the Holy Trinity tells us that God is not alone. He is a communion and community of love where one Person donates himself perfectly and eternally to the other two. And not just that. God wants to share this communion of love with all his creatures already in this life.
Well, someone may ask how it is possible to have such experience for us human, fallen and limited beings? The answer is quite simple: God shares his love with us in the Church and through the Church. Every time when we approach any of the sacraments, we come in contact with God’s mysterious presence among us. In the person of his Son and through the sacraments, God wanted to remain with us in a very tangible way. He comes to meet us in our concrete situation of life not just for a moment or to produce a certain feeling—he comes to transform our lives and to make of us participants of his divine life. So, that having drunk from this inexhaustible fountain of love we may make God’s presence in this world visible through lives. God who is invisible wants to make himself visible through those who sharing in his divine life—this is the mission of our Christian families, marriages, parishes, communities. The love of God making the Persons of the Holy Trinity perfectly one, extends itself to those who welcome it in their lives and to make them one in their marriage, families, communities. This is the simplest teaching on the Holy Trinity. When you don’t know what the Trinity is, look at your own family, which is called to be a reflection of that love and communion, although imperfect but still real.
