As Catholics, we believe that we can know the existence of God with certainty from the natural light of human reason. Many people do rely simply on a sense of the presence of God, but when the reality of God is challenged, we need not feel that our faith is simply an emotion.

The beauty of creation is one way in which God’s existence is evident to us. Catholics have also always welcomed the formal investigation of the world in what we call the sciences, and many of the great scientific discoveries have been made by people who share our faith. Science also shows us the beauty of creation.

We observe that the universe is a cosmos rather than a chaos, that it works according to laws and constants that operated long before there were any human beings to discover them and describe them mathematically. The universe, as we discover it to be, shows an order that speaks of a supreme intellect or mind at the origin of all things, which upholds all things in being. This supreme mind we call God.

From what He has revealed to us, we also know God to be personal, loving and merciful, but even without any appeal to the scriptures or to faith, belief in a supreme being is rational and in accord with the evidence. When we reflect on the immensity and complexity of the universe and the way in which we can make use of science to fashion new things, we can also thrill to the power of the mind of God the Creator. Let us praise, worship and adore Him.
