Existence of God
1. Man’s Religious Dimension
Throughout history, humans have shown a religious dimension.
All cultures reflect on God and the central themes of human existence.
The denial of God’s existence is a relatively recent phenomenon.
Indicators of God’s existence include:
Beauty and order in nature
Human capacity for self-reflection
Conscience and morality
The pervasive desire for happiness
According to the Catechism of the Catholic Church (CCC 27): "The desire for God is written in the human heart, because man is created by God and for God..."
2. Cosmological Proofs
The existence of God can be demonstrated through two main proofs:
Cosmological proofs: based on the observation of material creatures
Anthropological proofs: based on human nature
Cosmological arguments include:
Motion:
Some things are in motion or changing.
Everything in motion is moved by another.
Conclusion: There must be a First Mover (unmoved by another).
Causation:
Everything that is caused has a prior cause.
Conclusion: There must be a First Cause (uncaused).
Contingency:
Contingent beings cannot create themselves.
There must be a Necessary Being (from which all contingent beings proceed).
Perfection:
Varying degrees of perfection exist; they must derive from a Perfect Being.
Design:
Many beings without intelligence act towards an end; there must be an Intelligent Designer.
3. Anthropological Proofs
Spiritual Nature of Man:
Humans possess intellect, will, and a natural desire for happiness.
Conscience is inherent, indicating a moral framework.
4. Atheism: The Denial of God
Causes of atheism include:
Arguments for God’s existence are not as conclusive as those in sciences, making belief optional.
Religion is viewed as a form of oppression.
A sense of individualism leads to the belief that one does not need God.
Religion often only considered useful if it provides personal comfort.
Moral implications of belief in God can be undesirable.
Sin darkens human understanding, contributing to the difficulty in recognizing God (cf. CCC 37).
Types of Atheism
Theoretical Atheism: Denies God’s existence on a rational basis.
Practical Atheism: Lives as though God does not exist despite theoretical beliefs.
5. Agnosticism
Agnosticism maintains that human reason cannot definitively conclude anything about God’s existence.
