The Bible clearly speaks of: God the Son, God the Father, and God the Holy Spirit. But emphasizes that there is only ONE God.
If we were to use math, it would not be, 1+1+1=3. It would be 1x1x1=1. God is a triune God.•
◦God is three persons.
◦Each person is divine.
◦There is only one God.
Many theologians admit that the term “person” is not a perfect word to describe the three individual aspects/foci found in God. When we normally use the word person, we understand it to mean physical individuals who exist as separate beings from other individuals. But in God, there are not three entities nor three beings. God is a trinity of persons consisting of one substance and one essence. God is numerically one. Yet, within the single divine essence are three individual subsistences that we call persons.
•Each of the three persons is completely divine in nature though each is not the totality of the Godhead.
•Each of the three persons is not the other two persons.
•Each of the three persons is related to the other two but are distinct from them.
The word “trinity” is not found in the Bible, but this does not mean that the concept is not taught there. The word “bible” is not found in the Bible either, but we use it anyway. Likewise, the words “omniscience,” which means “all-knowing,” “omnipotence,” which means “all-powerful,” and “omnipresence,” which means “present everywhere” are not found in the Bible either; but we use these words to describe the attributes of God. So, to say that the Trinity isn’t true because the word isn’t in the Bible is an invalid argument.
Thus the term: “Tri” meaning three, and “Unity” meaning one, Tri+Unity = Trinity.
The most difficult thing about the Christian concept of the Trinity is that there is no way to perfectly and completely understand it. The Trinity is a concept that is impossible for any human being to fully understand, let alone explain. God is infinitely greater than we are; therefore, we should not expect to be able to fully understand Him. The Bible teaches that the Father is God, that Jesus is God, and that the Holy Spirit is God. The Bible also teaches that there is only one God. Though we can understand some facts about the relationship of the different Persons of the Trinity to one another, ultimately, it is incomprehensible to the human mind. However, this does not mean the Trinity is not true or that it is not based on the teachings of the Bible.
The doctrine of the Trinity means that there is one God who eternally exists as three distinct Persons — the Father, Son, and Holy Spirit. Stated differently, God is one in essence and three in person. These definitions express three crucial truths: (1) The Father, Son, and Holy Spirit are distinct Persons, (2) each Person is fully God, (3) there is only one God.
The Father, Son, and Holy Spirit are distinct Persons. The Bible speaks of the Father as God (Philippians 1:2), Jesus as God (Titus 2:13), and the Holy Spirit as God (Acts 5:3–4). Are these just three different ways of looking at God, or simply ways of referring to three different roles that God plays?
The answer must be no, because the Bible also indicates that the Father, Son, and Holy Spirit are distinct Persons. For example, since the Father sent the Son into the world (John 3:16), He cannot be the same person as the Son. Likewise, after the Son returned to the Father (John 16:10), the Father and the Son sent the Holy Spirit into the world (John 14:26; Acts 2:33). Therefore, the Holy Spirit must be distinct from the Father and the Son.
In the baptism of Jesus, we see the Father speaking from heaven and the Spirit descending from heaven in the form of a dove as Jesus comes out of the water (Mark 1:10–11). In John 1:1(HCSB)In the beginning was the Word, and the Word was with God, and the Word was God. it is affirmed that Jesus is God and, at the same time, that He was “with God,” thereby indicating that Jesus is a distinct Person from God the Father John 1:18(HCSB)No one has ever seen God.The One and Only Son—the One who is at the Father’s side— He has revealed Him.. And in John 16:13–15(HCSB)13 When the Spirit of truth comes, He will guide you into all the truth. For He will not speak on His own, but He will speak whatever He hears. He will also declare to you what is to come. 14 He will glorify Me, because He will take from what is Mine and declare it to you. 15 Everything the Father has is Mine. This is why I told you that He takes from what is Mine and will declare it to you. we see that although there is a close unity between them all, the Holy Spirit is also distinct from the Father and the Son.
Jesus is seated at the right hand of the Father
Romans 8:34(HCSB)Who is the one who condemns? Christ Jesus is the One who died, but even more, has been raised;He also is at the right hand of God and intercedes for us.
Acts 7:55-56(HCSB)55 But Stephen, filled by the Holy Spirit, gazed into heaven. He saw God’s glory, with Jesus standing at the right hand of God, and he said, 56 “Look! I see the heavens opened and the Son of Man standing at the right hand of God!”
Ephesians 1:20(HCSB)20 He demonstrated this power in the Messiah by raising Him from the dead and seating Him at His right hand in the heavens—
Colossians 3:1(HCSB)So if you have been raised with the Messiah, seek what is above, where the Messiah is, seated at the right hand of God.
Hebrews 1:3(HCSB) The Son is the radiance of God’s glory and the exact expression of His nature, sustaining all things by His powerful word. After making purification for sins, He sat down at the right hand of the Majesty on high.
Hebrews 8:1(HCSB)Now the main point of what is being said is this: We have this kind of high priest, who sat down at the right hand of the throne of the Majesty in the heavens,
Hebrews 10:12-15(HCSB)12 But this man, after offering one sacrifice for sins forever, sat down at the right hand of God. 13 He is now waiting until His enemies are made His footstool. 14 For by one offering He has perfected forever those who are sanctified. 15 The Holy Spirit also testifies to us about this. For after He says:
Hebrews 12:2(HCSB)2 keeping our eyes on Jesus, the source and perfecter of our faith, who for the joy that lay before Him endured a cross and despised the shame and has sat down at the right hand of God’s throne.
1 Peter 3:22(HCSB) Now that He has gone into heaven, He is at God’s right hand with angels, authorities, and powers subject to Him.
Matthew 22:44(HCSB)The Lord declared to my Lord,‘Sit at My right hand until I put Your enemies under Your feet’?
Acts 2:33(HCSB)33 Therefore, since He has been exalted to the right hand of God and has received from the Father the promised Holy Spirit, He has poured out what you both see and hear.
The fact that the Father, Son, and Holy Spirit are distinct Persons means, in other words, that the Father is not the Son, the Son is not the Holy Spirit, and the Holy Spirit is not the Father. Jesus is God, but He is not the Father or the Holy Spirit. The Holy Spirit is God, but He is not the Son or the Father. They are different Persons, not three different ways of looking at God.
Sometimes the Personhood of the Father and Son is appreciated, but the Personhood of the Holy Spirit is neglected. Sometimes the Spirit is treated more like a “force” than a Person. But the Holy Spirit is not an it, but a He
John 14:26(HCSB)26 But the Counselor, the Holy Spirit—the Father will send Him in My name—will teach you all things and remind you of everything I have told you.
John 16:7–15(HCSB)7 Nevertheless, I am telling you the truth. It is for your benefit that I go away, because if I don’t go away the Counselor will not come to you. If I go, I will send Him to you. 8 When He comes, He will convict the world about sin, righteousness, and judgment: 9 About sin, because they do not believe in Me; 10 about righteousness, because I am going to the Father and you will no longer see Me; 11 and about judgment, because the ruler of this world has been judged. 12 “I still have many things to tell you, but you can’t bear them now. 13 When the Spirit of truth comes, He will guide you into all the truth. For He will not speak on His own, but He will speak whatever He hears. He will also declare to you what is to come. 14 He will glorify Me, because He will take from what is Mine and declare it to you. 15 Everything the Father has is Mine. This is why I told you that He takes from what is Mine and will declare it to you.
The fact that the Holy Spirit is a Person, not an impersonal force (like gravity), is also shown by the fact that He speaks Hebrews 3:7-10(HCSB)7 Therefore, as the Holy Spirit says: Today, if you hear His voice, 8 do not harden your hearts as in the rebellion, on the day of testing in the wilderness,9 where your fathers tested Me, tried Me,and saw My works 10 for 40 years.Therefore I was provoked with that generation and said, “They always go astray in their hearts, and they have not known My ways.”, reasons Acts 15:28(HCSB)28 For it was the Holy Spirit’s decision—and ours—to put no greater burden on you than these necessary things: thinks and understands (1 Corinthians 2:10–11(HCSB)10 Now God has revealed these things to us by the Spirit, for the Spirit searches everything, even the depths of God. 11 For who among men knows the thoughts of a man except the spirit of the man that is in him? In the same way, no one knows the thoughts[b] of God except the Spirit of God., wills (1 Corinthians 12:11(HCSB)11 But one and the same Spirit is active in all these, distributing to each person as He wills., feels Ephesians 4:30(HCSB)30 And don’t grieve God’s Holy Spirit. You were sealed by Him for the day of redemption., and gives personal fellowship (2 Corinthians 13:14(HCSB)13 The grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with all of you.
These are all qualities of personhood. In addition to these texts, the others we mentioned above make clear that the Personhood of the Holy Spirit is distinct from the Personhood of the Son and the Father. They are three real persons, not three roles God plays.
Another serious error people have made is to think that the Father became the Son, who then became the Holy Spirit. Contrary to this, the passages we have seen imply that God always was and always will be three Persons. There was never a time when one of the Persons of the Godhead did not exist. They are all eternal.
While the three members of the Trinity are distinct, this does not mean that any is inferior to the other. Instead, they are all identical in attributes. They are equal in power, love, mercy, justice, holiness, knowledge, and all other qualities.
The Trinity is one God existing in three Persons. Understand that this is not in any way suggesting three Gods. Keep in mind when studying this subject that the word “Trinity” is not found in Scripture. This is a term that is used to attempt to describe the triune God—three coexistent, co-eternal Persons who make up God. Of real importance is that the concept represented by the word “Trinity” does exist in Scripture. The following is what God’s Word says about the Trinity:
2) The Trinity consists of three Persons (Genesis 1:1, 26; 3:22; 11:7; Isaiah 6:8, 48:16, 61:1; Matthew 3:16-17, 28:19; 2 Corinthians 13:14). In Genesis 1:1, the Hebrew plural noun “Elohim” is used. In Genesis 1:26, 3:22, 11:7 and Isaiah 6:8, the plural pronoun for “us” is used. The word “Elohim” and the pronoun “us” are plural forms, definitely referring in the Hebrew language to more than two. While this is not an explicit argument for the Trinity, it does denote the aspect of plurality in God. The Hebrew word for “God,” “Elohim,” definitely allows for the Trinity.
The individual members of the Trinity have different tasks. The Father is the ultimate source or cause of the universe (1 Corinthians 8:6; Revelation 4:11); divine revelation (Revelation 1:1); salvation (John 3:16-17); and Jesus’ human works (John 5:17; 14:10). The Father initiates all of these things.
The Son is the agent through whom the Father does the following works: the creation and maintenance of the universe (1 Corinthians 8:6; John 1:3; Colossians 1:16-17); divine revelation (John 1:1, 16:12-15; Matthew 11:27; Revelation 1:1); and salvation (2 Corinthians 5:19; Matthew 1:21; John 4:42). The Father does all these things through the Son, who functions as His agent.
The Holy Spirit is the means by whom the Father does the following works: creation and maintenance of the universe (Genesis 1:2; Job 26:13; Psalm 104:30); divine revelation (John 16:12-15(HCSB)12 “I still have many things to tell you, but you can’t bear them now. 13 When the Spirit of truth comes, He will guide you into all the truth. For He will not speak on His own, but He will speak whatever He hears. He will also declare to you what is to come. 14 He will glorify Me, because He will take from what is Mine and declare it to you. 15 Everything the Father has is Mine. This is why I told you that He takes from what is Mine and will declare it to you.
2 Peter 1:21(HCSB)21 because no prophecy ever came by the will of man; instead, men spoke from God as they were moved by the Holy Spirit.; salvation ; Titus 3:5(HCSB)He saved us—not by works of righteousness that we had done, but according to His mercy, through the washing of regeneration and renewal by the Holy Spirit.;
1 Peter 1:2(HCSB)2 according to the foreknowledge of God the Father and set apart by the Spirit for obedience and for sprinkling with the blood of Jesus Christ. May grace and peace be multiplied to you.
and Jesus’ works Isaiah 61:1(HCSB)The Spirit of the Lord God is on Me, because the Lord has anointed Me to bring good news to the poor. He has sent Me to heal the brokenhearted, to proclaim liberty to the captives and freedom to the prisoners;; Acts 10:38(HCSB)38 how God anointed Jesus of Nazareth with the Holy Spirit and with power, and how He went about doing good and healing all who were under the tyranny of the Devil, because God was with Him.. Thus, the Father does all these things by the power of the Holy Spirit.
If there is one passage which most clearly brings all of this together, it is Matthew 28:19(ESV) “Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit.” First, notice that the Father, Son, and Holy Spirit are distinguished as distinct Persons. We baptize into the name of the Father and the Son and the Holy Spirit. Second, notice that each Person must be deity because they are all placed on the same level. In fact, would Jesus have us baptize in the name of a mere creature? Surely not. Therefore each of the Persons into whose name we are to be baptized must be deity. Third, notice that although the three divine Persons are distinct, we are baptized into their name (singular), not names (plural). The three Persons are distinct, yet only constitute one name. This can only be if they share one essence.
“Do I have to believe in the Trinity to be saved?” The answer is yes and no. Does a person have to fully understand and agree with every aspect of Trinitarianism to be saved? No. Are there some aspects of Trinitarianism that play key roles in salvation? Yes. For example, the deity of Christ is crucially important to the doctrine of salvation. If Jesus is not God, His death could not have paid the infinite penalty of sin. Only God is infinite—He had no beginning, and He has no end. All other creatures, including angels, are finite; they were created at some point. Only the death of an infinite Being could atone for the sin of mankind throughout eternity. If Jesus is not God, He could not be the Savior, the Messiah, the Lamb of God who takes away the sin of the world John 1:29(HCSB)29 The next day John saw Jesus coming toward him and said, “Here is the Lamb of God, who takes away the sin of the world!. An unbiblical view of Jesus’ divine nature results in an errant view of salvation. Every “Christian” cult that denies the true deity of Christ also teaches that we must add our own works to Christ’s death in order to be saved. The true and full deity of Christ, an aspect of Trinitarianism, refutes this concept.
1. The Trinity is not belief in three gods. There is only one God, and we must never stray from this.
2. This one God exists as three Persons.
3. The three Persons are not each part of God, but are each fully God and equally God. Within God’s one undivided being there is an unfolding into three interpersonal relationships such that there are three Persons. The distinctions within the Godhead are not distinctions of His essence and neither are they something added onto His essence, but they are the unfolding of God’s one, undivided being into three interpersonal relationships such that there are three real Persons.
4. God is not one person who took three consecutive roles. That is the heresy of modalism. The Father did not become the Son and then the Holy Spirit. Instead, there have always been and always will be three distinct persons in the Godhead.
5. The Trinity is not a contradiction because God is not three in the same way that He is one. God is one in essence, three in Person.
