The Pope said this today before praying the midday Angelus with those gathered in St. Peter's Square, in which he offered a reflection on the Trinity "as it was made know to us by Jesus."
Christ revealed that "God is love 'not in the unity of a single person, but in the Trinity of a single substance,'” the Holy Father said, quoting the preface.
"The Trinity is Creator and merciful Father; Only Begotten Son, eternal Wisdom incarnate, dead and risen for us; it is finally the Holy Spirit, who moves everything, cosmos and history, toward the final recapitulation," the Pontiff explained. "Three Persons who are one God because the Father is love, the Son is love, the Spirit is love. God is love and only love, most pure, infinite and eternal love."
"The Trinity does not live in a splendid solitude," he added, "but is rather inexhaustible font of life that unceasingly gives itself and communicates itself."
Benedict XVI said one could get a sense of the Trinity simply by observing nature from the most elementary cellular levels to the planets, stars and galaxies.
"The 'name' of the Most Holy Trinity is in a certain way impressed upon everything that exists, because everything that exists, down to the least particle, is a being in relation, and thus God-relation shines forth, ultimately creative Love shines forth," he said.
"All comes from love, tends toward love, and is moved by love, naturally, according to different grades of consciousness and freedom," the Pope affirmed.
"Every being," he continued, "by the very fact of existing and by the 'fabric' of which it is made, refers to a transcendent Principle, to eternal and infinite Life that gives itself, in a word: to Love."
Benedict XVI affirmed that there is proof that human beings are made in the image of the Trinity, because "only love makes us happy, because we live in relation, and we live to love and be loved."
"Using an analogy suggested by biology," he concluded, "we could say the human 'genome' is profoundly imprinted with the Trinity, of God-Love.”
