How do we know God?
We know God from the things he has created. First, we look at the things in the world and discover that they are moved, caused, have goodness, beauty, and order, etc., and from this we can come to a knowledge of God as the origin and the end of the universe. Second, the human person has an openness to truth and beauty, a sense of moral goodness, as well as freedom and an inner “voice” of conscience. In these the human person discerns signs of his or her soul that are “seeds of eternity” which have their origin in God (Catechism of the Catholic Church, nn. 31-35).
We can also know God from the Church’s proclamation of the special revelation that God has given of himself throughout human history. This revelation is found in Sacred Scripture and Sacred Tradition. The climax of this revelation comes in Jesus Christ: “through His words and deeds, His signs and wonders, but especially through His death and glorious resurrection from the dead and final sending of the Spirit of truth.” This special revelation tells us that “God is with us to free us from the darkness of sin and death, and to raise us up to life eternal” (Dogmatic Constitution on Divine Revelation: Dei verbum, n. 4).
