It is just impossible for the human mind to comprehend God. But we do need to know something about God, or else He would remain just an empty word with no meaning. The only way to express this is through a mystery. God remains a mystery because we cannot comprehend Him totally, like other mysteries of the universe acts, like an attention magnets that keeps producing questions and eliciting presumably better and better answers. Because mysteries are intelligelible, we keep thinking about them. Because mysteries never have fully satisfying explanations we keep pondering on them.
When our faith claims that something is a mystery, it is not for us to suspend our thinking and leave it for theologians or experts in the Catholic doctrine. It is for us to think and, in thinking, loving. None of us, no matter how enlightened a theologian one can be, is going to scream, “Eureka! I solved the puzzle!” Still all of us are called to ask “Who is God really?” because how we live will depend on the answer we give to that fundamental question.
If God is just one more member of a god’s club that tries to enjoy his divine life in the Olympo, chances are, we will understand our life as a survival feat, trying to get the best out of the gods and trying to get away from the wrath and whims.
If God is just one powerful being out there and He permits evil without moving a finger, I, in my freedom, have the possibility to reject an almighty but inconsiderate God. I could choose to live and die away from that God, rather than constantly living in fear of Him, or associated with His merciless power.
If God is compassionate, but He still permits evil in the world, it seems that He is less powerful than evil, and I would also have the possibility of not associating myself with such a weak God.
So, who is God really? Again, we cannot know. No wonder the church took some three centuries to be able to formulate in a more precise language who God needs to be, to be both powerful and compassionate.
In fact, we do have clues that help us understand Him better. And the first clue comes from His Son. Perhaps the question of the nature of God is profound, but it seems that the question of Jesus Christ is more accessible.
So, who is Jesus Christ? If he is one more prophet who died, setting a good example of ultimate fidelity, we could be inspired by His example, but ultimately abandoned to our own strength to be faithful to God. Our salvation would still be an Old Testament salvation.
But if Jesus Christ is God made man, who became a victim of all the evil in the world: betrayed, misunderstood, abandoned, etc, things would be totally different. If His dying on the cross is not just one more error of justice condeming an innocent man, but a true sin against the God hanging on the cross, a cruel way of telling God, “Get out of our lives,” then God is not outside the history of evil. He is compassionate enough to endure our own evil with us.
However if God is not defeated by this sin, but powerful enough to conquer it by rising from the dead, then God is powerful. Powerful enough to conquer evil when the Father raises the Son, and compassionate enough when the Son is killed by sin.
So, we see how God is powerful because God is outside us, overcoming the greatest effect of evil: that of exiling God from our world. At the same time, we see that God is compassionate because compassion is “suffering with” and this is what Jesus Christ did– to suffer with us the effects of our own sins.
We can only reach these inevitable conclusions because we discovered Jesus Christ as God. So God, is not a solitary mind, but a Father and a Son, at the same time, powerful Creator and compassionate companion to humans.
But is this enough? Is compassion effective? If I have cancer and someone in the name of compassion, decides to have cancer like me to “accompany” me, does he rescue me from my cancer? Would not his compassion just create one more victim of the evil of cancer? Is God’s compassion, a feeble attempt or saving power?
Only if the power to raise Jesus from the dead is transfered within us, is our salvation something effective. Only if the power to overcome evil, is not only a kind of energy that circulates between the Father and the Son, but springs up overflowing into our hearts, making us adoptive children in the way the Son is son, then this compassion becomes a real divine power in us and for us. We call this power, the Spirit of God.
In other words, because God is three, our salvation is true. Because God is Father outside us, He can create and rule with power. Because God is Son with us, He can feel what we feel, and suffer what we suffer. Because God is Spirit in us, He can touch and transform our hearts giving them the power to actually conquer the evil that springs from them.
We do not know what God really is. Our feeble minds cannot comprehend him, but this much we need to hold: that for our salvation to be effective, God must be one, must be outside us, besides us and inside us: a Father creating and begetting, a Son redeeming and accompanying, a Spirit inspiring and restoring. Our faith is indeed a faith in the Father, the Son and the Holy Spirit.
