Is there a trinity in God?

No, there is no trinity in God.

"Hear O Israel, the LORD our God is one LORD." Deuteronomy 6:4

God does not divide Himself. He does not share His Glory with any other being (Isaiah 42:8, Isaiah 48:11). There are not three Gods or persons, but one distinct God. Apostolics like Jews are strict Monotheists, not Trinitarians, for the Bible teaches strict Monotheism.

When we say there is no trinity in God, we do not deny the Father, Son and Holy Ghost; we simply believe that these titles are all in Jesus. Hallelujah! The Bible states that the fullness of God dwells in Jesus bodily (Colossians 2:9). We should note that Father is not a name, Son is not a name, and Holy Spirit is not a name. These titles represent roles. God acts in the role of a father. The same God acts as the Holy Spirit, for God is holy and God is a Spirit. He then acts in the role of a Son. To operate as a Son, God incarnated Himself in the womb of the Virgin Mary and came forth as a man. (See Galatians 4:4 and Matthew 1:18-21).

Father, Son and Holy Ghost
When Jesus commanded His disciples to go and teach all nations, and to baptize them in the name of the Father, and of the Son and of the Holy Ghost in Matthew 28:19, he was not identifying three separate beings or Gods. He was simply emphasizing His declaration that all power is given to Him in heaven and in earth, which He proclaimed in the previous verse. Jesus is the one God and father of all, who has all power. He is the Son of God, and He is the Holy Spirit. Baptism should be performed in Jesus' name. The apostles to whom Jesus proclaimed the great commission understood Him clearly, for they all baptized believers in the name of Jesus. They did not repeat the titles, for they knew that Jesus is the one identified by the titles. (See Acts 2:38, Acts 4:12, Acts 8:35-38, Acts 10:48, Acts 16:30-33, Acts 19:5). Can you imagine? These chapters all speak of baptism, and it was always done is the name of Jesus. Do not let any man deceive you. The scriptures are plain and clear. The Bible also states:

"To wit, that God was in Christ, reconciling the world unto himself..." 2 Corinthians 5:19

God was fully in Christ by His Spirit, reconciling the world to Himself [God]. It takes flesh for man to see God or for God to express Himself to man as a lamb and savior of the world.

Jesus is the Father. How? Before Abraham was, Jesus exists as the ONE Spirit of God, which moved upon the face of the deep during creation (See Genesis 1:2 and John 8:58). At that time He was not identified by the name Jesus, but by the Hebrew YHWH (Yahweh or Jehovah). He later came as Jesus to save man from sin (Isaiah 7:14, Matthew 1:23). Jesus stated that the Father was in Him and He in the Father (See John 14:9-10). By His Spirit without measure or limit, God dwelled in the man Christ Jesus fully (John 3:34).

Jesus is the Son of God. God came as a man in flesh (See 1 Timothy 3:16). The body in which God came is known as the Son of God because this flesh was formed/fathered by God (Luke 1:35). The Sonship began when the Holy Spirit overshadowed the Virgin Mary and the child Jesus was formed in her womb. The Son or body was formed in the incarnation. We may use the term Son to say "the Son died," but we can never use the son to refer to God's deity or Spirit, for Son signifies flesh. There is no God the Son, for the Son is not eternal and God cannot die. Only the flesh or son of God died. In order to die for the sin of mankind, God had to veil or cover Himself in flesh. The title Son of God does not mean that Jesus is another person or being which is different from God. It simply is God in a visible form or God in flesh. Jesus is the Son of God in a way that no one else is or can ever be. His Sonship is different in kind. He does not merely resemble God in some limited ways, but He is equal to God in every way (Philippians 2:6). Indeed, the Son is "the image of the invisible God," "the brightness of his glory, and the express image of his person" (Colossians1:15; Hebrews 1:2-3).

Jesus is the only flesh or visible manifestation of God in the New Testament and the only God we will see in Heaven (Revelation 4:2). He now has a glorified body, which means it is spiritual. His body was glorified at His resurrection for Him to return to heaven (John 20:26, John 7:33). The Bible states that Jesus will come again in the glory of His fatheróthe glory of the one Spirit that formed Jesus in the womb of Mary (See Matthew 16:27). The same Jesus who came and died is the one who sits upon the one throne of rulership and authority in heaven in a glorified body. He will return to earth in the full glory of the one Spirit of God, slaying the Antichrist in the process, and will rule forever as King of kings and Lord of lords (Zachariah14:1-7, 2 Thessalonians 2:8).

Jesus is the Holy Ghost. The title Holy Ghost is used interchangeably with Holy Spirit. It simply means that God is Holy and God is a Spirit (John 4:24). It refers to God in activity. For example, God moved upon the face of the deep during creation (Genesis 1:2). In activity, God fills the life of a believer by his Spirit, which is evidenced initially by new tongues; in this case, we say the believer is filled with the Holy Spirit. In addition, God by his Spirit regenerates, sanctifies, and anoints humanity. The Holy Spirit is no different from the one God Himself. He is not a second person in a trinity. Jesus is the Spirit of God, for Jesus was human and divine (Humanity and deity) See 1 Timothy 3:16 and Hebrews 10:20. As the Spirit, He transfigured on the Mount of Olives and operates in heaven and on earth at the same time (Matthew 17:2, John 3:13). God cannot be divided. He declared that he will not give His one glory to another being. (See Deuteronomy 6:4, Isaiah 42:8, Isaiah 48:11).

Explanation of 1 John 5:7

" For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one" 1 John 5:7

Let us note that the title Son is not mentionedóWord is mentioned instead. The three words Father, Word and Holy Ghost can all refer to the Spirit of God. God by his Spirit fathered Jesus as a man (Matthew 1:21, Luke 1:35). The Word, as in John 1:1, was translated from the Greek word logos, which means the thought, plan, or mind of God and also the expression of God. Holy Ghost is no different from God, for God is holy and God is Spirit. The verse also states that these three are one. There is only one God, so the verse makes itself plain that these titles are referring to the one true God, which is indivisible. Some Trinitarians will say that the verse speaks of unity of God as with a wife and husband. This refutes the strict monotheism taught by the Bible. The view of God being three persons is non-biblical and polytheistic. Deuteronomy 6:4 states that there is only one God. God is one distinct Spirit and He expressed Himself as a man solely for the purpose of redemption. Jesus is the express image of God's person (Hebrews 1:3). Jesus is not one of the express images of God's person or persons. He is the express image (singular) of the one God.
