The concept of "One-God" is central to the monotheistic faith of Christianity, rooted deeply in the biblical narrative and theology. This belief asserts the existence of a single, all-powerful, and sovereign deity who is the creator and sustainer of the universe. The doctrine of monotheism is foundational to the Christian understanding of God and is consistently affirmed throughout the Scriptures.

Old Testament Foundations

The Shema, found in Deuteronomy 6:4, is a pivotal declaration of the oneness of God: "Hear, O Israel: The LORD our God, the LORD is One" . This proclamation not only affirms the singularity of God but also serves as a call to exclusive worship and devotion to Him. The Old Testament consistently emphasizes God's unique nature and His distinction from the gods of surrounding nations. Isaiah 45:5 states, "I am the LORD, and there is no other; there is no God but Me" , underscoring the exclusivity of Yahweh as the one true God.

New Testament Affirmation

The New Testament continues to affirm the oneness of God while also revealing the complexity of His nature through the doctrine of the Trinity. In Mark 12:29, Jesus reiterates the Shema, affirming the oneness of God: "The most important commandment is this: ‘Hear, O Israel, the Lord our God, the Lord is One’" . The Apostle Paul also emphasizes monotheism in 1 Corinthians 8:4-6, where he acknowledges the existence of many so-called gods but affirms, "yet for us there is but one God, the Father, from whom all things came and for whom we exist" .

Theological Implications

The belief in one God has profound theological implications for Christian doctrine and practice. It establishes the basis for God's sovereignty, as there is no other deity to rival His power or authority. This belief also underpins the moral and ethical teachings of the Bible, as God's singular nature demands exclusive allegiance and worship. The oneness of God is integral to the understanding of His attributes, such as omnipotence, omniscience, and omnipresence, which are unique to Him alone.

Worship and Devotion

The monotheistic belief in one God calls for a life of worship and devotion that is centered on Him alone. The First Commandment, "You shall have no other gods before Me" (Exodus 20:3), reflects the demand for exclusive worship. This commandment is not merely a prohibition against idolatry but an invitation to a relationship with the one true God, characterized by love, obedience, and reverence.

Conclusion

The doctrine of one God is a cornerstone of Christian faith, shaping the believer's understanding of God's nature, His relationship with humanity, and the call to worship Him alone. This belief is deeply embedded in the biblical narrative, from the Old Testament's foundational declarations to the New Testament's affirmations, and continues to be a defining element of Christian theology and practice.
