All good Catholic theology and philosophy acknowledge that God is beyond knowing. He is utterly beyond our understanding, and beyond every concept we could ever come up with. It is to the point that, according to St Thomas Aquinas, we don’t even know what it means when we say that God exists.
So then, how are we supposed to love the Lord with all our hearts, minds, souls and strength? How can we love what we cannot know? What would such a love even look like?
To love is to desire the good of the other. That is, it is to desire the good that the other themselves are, to desire them to exist more fully, to come into their perfection and fulness. It also includes the desire of this good for ourselves.
What can we know of God? We know God as He reveals Himself, firstly in creation, in which every creature reflects something of God; secondly in the inspired scriptures, in which we see God moving and hear God speaking throughout history; thirdly in His Son, Jesus Christ, the fulness of God’s self revelation and action in history. And yet, all of this revelation does not negate the truth that God is completely beyond our power to know. So what does all of this revelation even reveal?
It tells us that God is love. That creation is loved into being, and exists as a reflection of His boundless goodness. That He cares for us, and moves within our history. That He is totally with us, joined in our joys and sufferings, giving Himself to us entirely.
We cannot grasp what God is. In fact, God is not a what at all. We cannot grasp Him because He is perfect self emptying love, pouring Himself out through all of eternity. You try to grasp Him and He has already gone, already fully emptied. We only know that He is, because we see how He fills up everything else.
So what is it to love the unknowable God? It is to desire His love to be fully expressed and received, both within ourselves and within all of creation. It is to surrender ourselves to His love for us, and be immersed in and transformed into His indiscriminate love for us all.
God bless you!
Beloved, let us love one another, because love is from God; everyone who loves is born of God and knows God. Whoever does not love does not know God, for God is love. God’s love was revealed among us in this way: God sent his only Son into the world so that we might live through him. In this is love, not that we loved God but that he loved us and sent his Son to be the atoning sacrifice for our sins. Beloved, since God loved us so much, we also ought to love one another. No one has ever seen God; if we love one another, God lives in us, and his love is perfected in us.[1 John 4:7-12]
