Outline of Systematic Theology (II) — Theology Proper (The Doctrine of God)

Chapter 1: Theology Proper — The Being of God
I. The Existence of God

  1. Cosmological Argument (因果论):
    Every effect has its cause; the existence of the universe points to a Creator.
  2. Teleological Argument (目的论):
    The order, harmony, and purpose evident throughout the natural world testify to an intelligent designer behind creation.
  3. Anthropological Argument (人类论):
    The complexity of the human body and the existence of human attributes—conscience, intellect, emotion, and will—point to the existence of an all-powerful and benevolent God.
  4. Moral Argument (道德论):
    The human sense of right and wrong and moral awareness reveal the reality of a moral Being—God.
  5. Ontological Argument (本体论):
    Human reason cannot conceive of a perfectly great Being that does not exist; therefore, the very idea of a perfect God implies His real existence.
  6. Universal Religious Argument (宗教论):
    Across all nations, tribes, and cultures, there exists universal religious worship, which points to the existence of the One being worshipped—God.

II. False Theories Concerning God

Atheism – Denial of the existence of God.

Agnosticism – Claim that the existence of God is unknowable.

Evolutionism – Belief that life and the universe arose by natural processes, not divine creation.

Polytheism – Belief in many gods.

Pantheism – Belief that everything in the universe is God.

Deism – Belief in a distant Creator who does not intervene in the world.
