Where in the Bible does it mention the Father, Son, and Holy Spirit together?

The doctrine of the Trinity, which posits that God is one being in three persons—Father, Son, and Holy Spirit—is a cornerstone of Christian theology. While the term "Trinity" itself does not appear in the Bible, the concept is derived from various passages where the three persons are mentioned together, illustrating their distinct roles yet unified essence. Let's explore some of these key scriptural references to understand how the Bible presents the Father, Son, and Holy Spirit together.

One of the most explicit mentions of the Trinity is found in the Great Commission given by Jesus to His disciples in the Gospel of Matthew. In Matthew 28:19, Jesus commands, "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." This verse is significant because it places the three persons of the Godhead on equal footing, indicating their co-equality and co-eternity. The use of the singular "name" rather than "names" underscores the unity of the three persons in one divine essence.

Another important passage is found in the Gospel of John, where Jesus speaks of the coming of the Holy Spirit. In John 14:16-17, Jesus says, "And I will ask the Father, and He will give you another Helper, to be with you forever, even the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him. You know Him, for He dwells with you and will be in you." Here, Jesus (the Son) speaks of asking the Father to send the Holy Spirit, thus showing the interaction and distinct roles of each person within the Godhead.

The baptism of Jesus, recorded in the Synoptic Gospels, also provides a vivid depiction of the Trinity. In Matthew 3:16-17, we read, "And when Jesus was baptized, immediately He went up from the water, and behold, the heavens were opened to Him, and He saw the Spirit of God descending like a dove and coming to rest on Him; and behold, a voice from heaven said, 'This is My beloved Son, with whom I am well pleased.'" In this scene, the Father speaks from heaven, the Son is baptized, and the Holy Spirit descends like a dove, offering a clear manifestation of the three persons of the Trinity.

Paul's epistles also contain Trinitarian references that help to elucidate the concept. In 2 Corinthians 13:14, Paul concludes his letter with a benediction: "The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with you all." This blessing not only mentions all three persons but also highlights their distinct roles in the life of believers—grace from the Son, love from the Father, and fellowship with the Holy Spirit.

Another Pauline reference is found in Ephesians 4:4-6, where Paul writes, "There is one body and one Spirit—just as you were called to the one hope that belongs to your call—one Lord, one faith, one baptism, one God and Father of all, who is over all and through all and in all." Here, Paul speaks of the Spirit, the Lord (Jesus), and God the Father, again emphasizing their unity and distinctiveness.

In the Old Testament, while the Trinity is not as explicitly revealed, there are hints and foreshadowings of this complex unity. For instance, in Genesis 1:26, God says, "Let us make man in our image, after our likeness." The plural pronouns "us" and "our" suggest a multiplicity within the Godhead. Additionally, the appearances of the Angel of the Lord, who is often identified with God yet distinct from God, and the Spirit of God, who is active in creation and prophecy, provide early glimpses of the Trinitarian nature of God.

The early church fathers also recognized and articulated the Trinitarian understanding of God based on these and other scriptural references. In his work "On the Trinity," Augustine of Hippo wrote extensively about the relationship between the Father, Son, and Holy Spirit, emphasizing their co-equality and co-eternity. Augustine argued that the Trinity is a mystery that can be apprehended through faith and reason, even if it cannot be fully comprehended by the human mind.

Furthermore, the Nicene Creed, formulated in AD 325 and revised in AD 381, is a historic confession of faith that articulates the Trinitarian belief. It states, "We believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible. And in one Lord Jesus Christ, the only-begotten Son of God... And in the Holy Spirit, the Lord and Giver of life, who proceeds from the Father [and the Son]." This creed reflects the church's understanding of the biblical revelation of the Trinity and has been a foundational statement of Christian orthodoxy for centuries.

In summary, while the Bible does not use the term "Trinity," it provides numerous references where the Father, Son, and Holy Spirit are mentioned together, revealing their distinct roles and their unity as one God. Passages such as the Great Commission (Matthew 28:19), Jesus' promise of the Holy Spirit (John 14:16-17), Jesus' baptism (Matthew 3:16-17), and Paul's benedictions (2 Corinthians 13:14; Ephesians 4:4-6) are key scriptural foundations for the doctrine of the Trinity. The early church's reflection on these texts, as seen in the writings of the church fathers and the formulation of the Nicene Creed, further solidifies the Trinitarian understanding of God as one being in three persons.
