“The person of the Holy Spirit was of such authority and dignity, that saving baptism was not complete except by the authority of the most excellent Trinity of them all, that is, by the naming of Father, Son, and Holy Spirit, and by joining to the unbegotten God the Father, and to his only-begotten Son, the name also of the Holy Spirit.”      ~ Origen

I was looking for something to reflect upon with regard today’s solemnity and I went to Pope Benedict to see what he said. Here is an excerpt from his June 7, 2009 Angelus address:

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” (Preface). 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. All things derive from love, aspire to love and move impelled by love, though naturally with varying degrees of awareness and freedom. “O Lord, our Lord, how majestic is your name in all the earth!”

Finally, I would suggest that at Sunday Mass (or later in a quiet place) when contemplating the awesome gift of the Eucharist, let us be united with the Church when the priest prays: May the reception of this sacrament, O Lord our God, and also the confession of our faith in the holy everlasting Trinity and of the undivided Unity of the same, profit us for the salvation of body and soul.
