Concerning a trinity let us take a gander at these scriptures.
1 Corinthians 8:6 But to us there is but one God, the Father, of whom are all things, and we in him.
Ephesians 4:6 One God and Father of all, who is above all, and through all, and in you all.
The Bible only attributes the Father as God.
Isaiah 9:6 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.
The Bible says the Son shall be called the everlasting Father.
John 14:8 Philip saith unto him, Lord, shew us the Father, and it sufficeth us.
John 14:9 Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father?
John 14:10 Believest thou not that I am in the Father, and the Father in me? the words that I speak unto you I speak not of myself: but the Father that dwelleth in me, he doeth the works.
Jesus said the Father that dwells in Him does the works.
But if the Son is God in flesh why does He need the Father to do the works.
Matthew 1:20 But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost.
If the Son came in flesh why was Mary conceived of the Holy Spirit.
That would make Him the Holy Spirit in flesh not God the Son in flesh.
Romans 1:3 Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh.
Galatians 4:4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law.
It appears the Son is the man Christ Jesus.
Not a trinity but one God who is a Holy Spirit, and Father is a title for God, and the Son is the man Christ Jesus.
The 3 relationships God has with His saints designated by titles.
Father- Creator and parent of the saints.
Son- God's visible relationship to the saints.
Holy Spirit- God's invisible relationship to the saints.
John 5:43 I am come in my Father's name, and ye receive me not: if another shall come in his own name, him ye will receive.
Hebrews 1:4 Being made so much better than the angels, as he hath by inheritance obtained a more excellent name than they.
John 14:26 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.
Jesus came in the Father's name.
The Son inherited the name from the Father.
The Holy Ghost comes in the name of Jesus.
Matthew 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost.
Those are titles and name is singular.
Jesus is the name.
Acts 2:38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
Acts 8:14 Now when the apostles which were at Jerusalem heard that Samaria had received the word of God, they sent unto them Peter and John:
Acts 8:15 Who, when they were come down, prayed for them, that they might receive the Holy Ghost:
Acts 19:1 And it came to pass, that, while Apollos was at Corinth, Paul having passed through the upper coasts came to Ephesus: and finding certain disciples,
Acts 19:3 And he said unto them, Unto what then were ye baptized? And they said, Unto John's baptism.
Acts 19:4 Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus.
Acts 19:5 When they heard this, they were baptized in the name of the Lord Jesus.
Jews, Samaritans, and Gentiles were baptized in the name of Jesus.
Colossians 3:17 And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by him.
Everything we do in word or deed is to be done in Jesus' name.
So why would we baptize in the titles.
1. Adam made in the image of God.
New Testament Adam was made in the fashion of Christ the image of God is the image of Christ.
In the beginning was the Word and the Word became flesh.
Which the Word was the plan of God in the beginning to come in the future in flesh.
So God created Adam in the image that He would appear in the future.
Let us make man in our image is God the Father and the man Christ Jesus.
2.
Revelation 4:2 And immediately I was in the spirit: and, behold, a throne was set in heaven, and one sat on the throne.
Revelation 22:3 And there shall be no more curse: but the throne of God and of the Lamb shall be in it; and his servants shall serve him.
There is only 1 throne in heaven not 2.
Which is the throne of God and the Lamb who is God in the glorified body of the man Christ Jesus.
Jesus is the only person we will see in heaven which if you have seen Him then you have seen the Father for He is a visible image of the Father.
There is one God and one Mediator between God and men the man Christ Jesus.
Jesus said all power was given to Him in heaven and earth.
God's right hand represents power, wisdom, and salvation.
David said the LORD said unto my Lord sit at my right hand "until" your enemies become your footstool.
For the Son must reign until His enemies are conquered and when that happens then the Son shall submit to God that God may be all in all.
So the Son at the right hand is a temporary role.
God exalted the man Christ to exercise the throne of power because He is the Mediator be at His right hand.
And when His enemies are conquered the Son shall stop being at the right hand that God may be all in all.
The 7 Churches in Revelation is how the Church age will go in popular influence.
Which the first Church was not caring about the poor like when they first started.
2,3, and 4 is the Roman Catholic Church which they were a popular influence for many years and became worse adding more falsehood.
The fifth Church is the Protestant movement but their works were not found perfect as they were still influenced by beliefs of the Catholic Church.
Which one was they were still holding on to the false belief of a trinity.
Jesus did not have a problem with the sixth Church which they were in the truth which included not believing in a trinity which was increasing.
The 7th Church was hypocritical and loved money and material things which we see popular now.
There is no trinity which the Catholic Church started that.
It is obvious when the Roman Empire embraced Christianity they did not get rid of their pagan and occult ways and it became their foundation for interpreting scriptures.
Which they believed the pagan belief of a trinity and had a female goddess Mary which they called Queen of heaven.
