For there are THREE that bear record in heaven, (1) the Father, (2) the Word, and (3) the Holy Ghost: and these three are ONE. (1 John 5:7)
In this scripture verse, some denominations use the term “Holy Trinity” to describe the Lord.
However, the Bible does not contain the phrase "Holy Trinity," nor does it reference the word "trinity." The term "trinity" originated in the eleventh century between 1175 and 1225 AD. It originates in Middle English, derived from Old French and Late Latin "trinitas," signifying a triad, trio, or the concept of a trinity. This term can be dissected to "trin-us," indicating threefold or a threesome, which eventually evolved into the concept and use of the term “Trinity.” In the Bible, the term used to describe the Father, the Son (Word), and the Holy Ghost is “the Godhead” (Acts 17:29; Rom 1:20; Col 2:9). When discussing the scriptures, we must use the language of the Bible.
Most Christian denominations accept the doctrine of the Father, the Son, and the Holy Ghost. However, there are some denominations that do not believe that God chooses to function as a Triune being. This theological disagreement often stems from where individuals receive their spiritual guidance. Some believers adhere to the teachings of their seminary professors, local pastors, Sunday school teachers, or online ministries, whose teachings sometimes have no scripture support. That is why every believer must first be taught by the primary teacher Jesus designated to believers, the Holy Spirit. A believer’s greatest need is the indwelling presence of the Holy Spirit—but without Him, it is equally their greatest lack. The Holy Spirit will never rebel against what God says. Jesus stated that the Holy Spirit is the believers' primary teacher, and John records that fact in both his gospel account and epistle. He writes:
But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you. (John 14:26)
Howbeit when he, the Spirit of truth, is come, he will guide you into all truth. (John 16:13)
But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him. (1 John 2:27)
When Jesus gave the disciples the Great Commission, He unveiled the structure of the divine self-governing body, instructing them as follows, “Go ye therefore, and teach all nations, baptizing them in the name of (1) the Father, and of (2) the Son, and of (3) the Holy Ghost” (Matt 28:19). The Godhead does not consist of three separate Gods. Building on 1 John 5:7, we can envision the Lord in this manner: God is a single entity who manifests three distinct personalities and operates within all three of these identities. The Father, the Son (Word), and the Holy Ghost possess the same essence, bear the same authority, and have the same abilities. This unity is grounded in this declaration, “Hear, O Israel: The LORD our God is one LORD” (Deut 6:4; Mark 12:29).
One can consider an analogy of a person with multiple personalities to comprehend this concept more effectively. In this case, the individual remains one person but exhibits various characters coexisting within them. In a similar yet profoundly positive manner, God is one divine being who reveals Himself as three distinct individuals: the Father, the Son, and the Holy Spirit. The Bible asserts that when the Lord incarnates to redeem humanity, the Father and the Son are the same. Isaiah writes:
For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace. (Isa 9:6)
In the embodiment of Jesus Christ, God manifested Himself as the Son (Ps 45:7; Heb 1:9). However, upon closer examination, it becomes evident that Jesus, the Son, is also described as “The everlasting Father” (Isa 9:6). During the Lord’s earthly ministry, the scriptures reveal Christ functioning both as the Son and the Father. An example of this duality can be found in the story of the woman who had been suffering from an issue of blood for twelve years. By faith, she touched the hem of Jesus’ garment, harnessed the anointing, and used the power of God to heal her body.
When Jesus turned and addressed the trembling woman, He did not call her “miss,” “ma’am,” “woman,” or “sister.” Instead, He affectionately called her “daughter” (Matt 9:20–22; Mark 5:25–34; Luke 8:43– 48). In that moment, the Son was distinctively acting as the Father. The Greek number and word for “daughter” are 2364 Θυγάτηρ thugatēr (thoo-gat'-air), “primary word; a female child, descendant (or inhabitant): - daughter.”
A similar thing occurred involving the man “sick of the palsy” (paralyzed). Instead of the Lord calling him “mister,” “sir,” or “brother,” Jesus referred to him as “son” (Matt 9:1–2; Mark 2:1-5), once again demonstrating His function as the first person of the Godhead, the Father. In Luke 5:20, Jesus referred to him as “man.” This variation in terminology between Matthew, Mark, and Luke does not represent a contradiction but rather a revelation by the Holy Spirit of God's original relationship with Adam. God not only created Adam and called him “Man” but also with the intention that “Man” would be His “Son” (Gen 1:26-28; Luke 3:38).
