We must affirm that there is one God who exists in three distinct persons–Father, Son and Holy Spirit, who are equal in glory, majesty and power. This is how God reveals himself in his word.
It is common to hear people claim that Christians, Jews, and Muslims all worship the same God. Not true. Unlike those who worship Allah, or those Jews who claim to worship the God of Abraham, Christians worship the true and living God, who reveals himself in three persons as Father, Son, and Holy Spirit.
It has been said that the Holy Trinity is Christianity’s most distinctive doctrine. Although in many ways the doctrine of the Trinity is beyond our comprehension, we believe this doctrine because this is how God reveals himself to us in his word, as Father, Son, and Holy Spirit, who are the one true God.
The doctrine of the Trinity is a difficult topic to discuss, because it stretches the limits of human language and logic. Despite the difficulties this doctrine presents to us, we must believe and confess that God is triune, because this is how God reveals himself to us in his word.
The three persons of the Godhead are revealed as equal in divinity, glory, and majesty. Each of the three persons are expressly called “God” in the New Testament. And to each of them is assigned the same divine attributes (i.e., simplicity, aseity, immutability), as well as the same glory and majesty which are ascribed to the other persons of the Trinity.
The Scriptures reveal that there is only one God. In Deuteronomy 6:4, Moses declares “Hear, O Israel: The Lord our God, the Lord is one.” In Isaiah 44:6, we read “I am the first and I am the last; besides me there is no god.” This same assertion is found throughout the New Testament, even though we learn of three distinct persons in the Godhead, Father, Son and Holy Spirit. In 1 Corinthians 8:4-6, Paul writes, “there is no God but one. For although there may be so-called gods in heaven or on earth—as indeed there are many `gods’ and many `lords’—yet for us there is one God, the Father, from whom are all things and for whom we exist, and one Lord, Jesus Christ, through whom are all things and through whom we exist.” Elsewhere James writes, “you believe that God is one; you do well. Even the demons believe—and shudder!” (James 2:19). The Scriptures are crystal clear, there is but one God.
Yet the Bible plainly teaches that although there is one God, he is revealed in three persons, Father, Son, and Holy Spirit. The three persons of the Godhead are mentioned together throughout the New Testament. When Jesus is baptized by John the Baptist, the Father declares, “this is my beloved Son, with whom I am well pleased,” even as the Spirit of God descended upon Jesus as a dove (Matthew 3:16-17). In Matthew 28:19, Jesus commands his disciples to “go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.” The mission of the church is to go into the world and make disciples by baptizing them in the name (singular) of three persons of the Godhead (Father, Son, and Holy Spirit).
