Why Do Christians Believe in Only One God?

 

 

Christianity is rooted in the belief that there is only one true God, a foundational teaching that permeates both the Old and New Testaments. This belief is not arbitrary but is supported by logical, philosophical, and theological reasoning. Below is an exploration of this belief, focusing on Scripture, reason, and deduction.


1. Biblical Foundation for One God

Old Testament Affirmation:

·    Deuteronomy 6:4 – “Hear, O Israel: The Lord our God, the Lord is one.”

o    This verse, known as the Shema, is the central declaration of Jewish monotheism, which Christians inherit.

·    Isaiah 45:5-6 – “I am the Lord, and there is no other; besides me, there is no God.”

o    God declares His exclusivity, leaving no room for the existence of other deities.

New Testament Affirmation:

·    1 Corinthians 8:6 – “Yet for us there is but one God, the Father, from whom all things came and for whom we live.”

o    Paul reaffirms monotheism in light of Jesus’ revelation.

·    James 2:19 – “You believe that there is one God. Good! Even the demons believe that—and shudder.”

o    Even the enemies of God acknowledge His singularity.


2. Logical Deductions: Why There Can Be Only One God

A. The Nature of Omnipotence

·    To be God means to be all-powerful (omnipotent), which entails having unlimited power.

·    If there were two or more gods, both possessing omnipotence, they would each be able to override the other’s power.

·    However, two omnipotent beings cannot coexist because true omnipotence means the ability to do all things without limitation. If one could limit or contradict the other, neither would be truly omnipotent.

·    Logical Deduction: Since omnipotence cannot be divided or shared, only one being can possess ultimate power, making multiple gods logically impossible.

B. Unity and Simplicity of God

·    God is simple (in theological terms), meaning that He is not composed of parts, and His attributes are inseparable from His being.

·    If there were multiple gods, they would necessarily be composed of different attributes or powers to distinguish them, contradicting the concept of divine simplicity.

·    Logical Deduction: Since God’s nature is simple and indivisible, plurality in the divine being is impossible.

C. Necessity of One Ultimate Cause

A first cause must exist to explain the existence of the universe (the Cosmological Argument).

 

If multiple gods existed, they would either:

o    Need to cooperate to create and sustain the universe, implying dependency.

o    Be independent, leading to a divided reality, which contradicts the observable unity and order of creation.

·   Logical Deduction: Since there is one universe governed by consistent laws, it follows that there must be one ultimate, uncaused cause—God.

D. Moral Authority and Unity of Goodness

·    If there were multiple gods, there would be multiple standards of morality and justice, which would lead to chaos and contradiction.

·    Objective moral law requires a singular, unchanging source.

·    Logical Deduction: A single, omnibenevolent God ensures that moral truth remains absolute and unchanging.


3. Philosophical Consistency: Occam’s Razor

  • Occam’s Razor states that the simplest explanation that adequately accounts for all phenomena is most likely true.
  • Positing one God explains the origin, order, and morality of the universe more efficiently than invoking multiple gods.
  • Logical Deduction: Monotheism is the most coherent and rational conclusion.

4. The Trinity: One God in Three Persons

  • While Christianity teaches the doctrine of the Trinity—Father, Son, and Holy Spirit—this does not imply three gods.
  • The Trinity describes one divine essence existing in three persons, preserving the oneness of God while accounting for the diversity of His self-revelation.
  • Logical Consistency: The Trinity maintains God’s oneness while providing a framework for understanding His relational nature.

Conclusion: The Necessity of One God

Christians believe in one God because:

  • Scripture unequivocally affirms it.
  • Philosophy and reason demonstrate that omnipotence, simplicity, and moral unity necessitate one God.
  • Creation and order in the universe point to a single, ultimate cause.

The belief in one God is not blind faith but a conclusion drawn from Scriptural truth and logical deduction that aligns with the nature of a perfect, omnipotent, and sovereign Creator.
