Sadly, because of the Fall, we also suffer the impact of Original Sin, which darkens our minds, weakens our wills, and inclines us to sin.
God has also given us a free will to seek and love what is true, good, and beautiful. He has given us an immortal soul and through the gifts of intelligence and reason enables us to understand the order of things established in his creation.
The most basic principle of the Christian moral life is the awareness that every person bears the dignity of being made in the image of God.
