Sometimes we can get the false idea that God somehow exists "outside" of the earth, as if he had a specific dwelling above the fluffy clouds we see in the sky.
While it is true that God exists outside of time and space, he is actually present in all of his creation. Every created thing, whether it is on earth or on the moon, contains within itself the presence of the Holy Trinity.
As the Catholic Encyclopedia points out, "The servant of God or the devout soul may be mindful of His presence in another way, namely, by the exercise of reason directed by faith. He sees God in the earth, the sea, the air and in all things."
Imprint of the Trinity
Pope Benedict XVI further expanded on this concept in an Angelus message on the Solemnity of the Holy Trinity in 2009:
[B]y 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.
He then explained how everything that exists contains a portion of the Trinity's 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!" (Ps 8: 1) the Psalmist exclaims.
Pope Benedict XVI argues that the greatest proof of God's love can be found in the human person:
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.
God is not a solitary being, but is communion itself, Father, Son and Holy Spirit. His very nature then calls us to communion with him, but also with each other. God desires that all may be one in him.
The Holy Trinity is still a great mystery that is difficult to comprehend. Similar to the world around us, it will take a lifetime to grasp even a small fraction of this mystery.
Only when we die will we ever be able to fully understand the mystery of the Trinity.
