Yesterday was the celebration of the Holy Trinity. What an immense blessing it is for Catholics who are able to recognized our bodies as a “home” for the Trinity when we sign ourselves: “In the name of the Father, and of the Son, and of the Holy Spirit.” Our baptism has indelibly marked our souls in the name of the Triune God.
Pope-Emeritus Benedict XVI wrote and spoke extensively regarding the Trinity. In 2009, he said this:
Today we contemplate the Most Holy Trinity as Jesus introduced us to it. He revealed to us that God is love “not in the oneness of a single Person, but in the Trinity of one substance.” He is the Creator and merciful Father; he is the Only-Begotten Son, eternal Wisdom incarnate, who died and rose for us; he is the Holy Spirit who moves all things, cosmos and history, toward their final, full recapitulation. Three Persons who are one God because the Father is love, the Son is love, the Spirit is love. God is wholly and only love, the purest, infinite and eternal love. He does not live in splendid solitude but rather is an inexhaustible source of life that is ceaselessly given and communicated. To a certain extent we can perceive this by observing both the macro-universe: our earth, the planets, the stars, the galaxies; and the micro-universe: cells, atoms, elementary particles. The “name” of the Blessed Trinity is, in a certain sense, imprinted upon all things because all that exists, down to the last particle, is in relation; in this way we catch a glimpse of God as relationship and ultimately, Creator Love. [emphasis added.]
It is amazing to contemplate the endless and “inexhaustible” life that is the Trinity, yet even more astounding that this life dwells in us! Indeed, the only way for this life to be “deadened” in us is through mortal sin. Not only that, but as Pope Benedict pointed out, the entire world is imprinted with this life. Imagine how radically different our world would be if each and every person recognized this and lived accordingly. Imagine how different your world would be if you recognized this and lived accordingly!
Pope Benedict also stated that we have clear evidence of the Trinity:
The strongest proof that we are made in the image of the Trinity is this: love alone makes us happy because we live in a relationship, and we live to love and to be loved. Borrowing an analogy from biology, we could say that imprinted upon his “genome”, the human being bears a profound mark of the Trinity, of God as Love.
One could say (although only as analogy) that our baptism “tattoos” the Trinity onto our souls. We are for all eternity marked, claimed for God: Father, Son and Holy Spirit. And this imprinting is pure love. Again, what a gift and blessing this is. God the Almighty – Father, Son and Holy Spirit – has claimed us and marked us for love for life, for eternity.
