1st what does the word trinity mean. A cording to Webster’s Dictionary it means “The unity of Father, Son, and Holy spirit in three persons, in one Godhead.”
The Bible clearly states that though there in only one God, He is manifested in three persons: Father, Son, Sprit. Each is independent of each other, but never do they act independently.
2nd What are the Characteristics that only God has
He is Eternal, no beginning, no end
He is Omnipotent, Unlimited Authority
He is Omnipresent, Present in all place and all times
He is Omniscient, all knowing
The last you i am going to mention is He has the ability to forgiver sin
All right now to adress a few things
1st
Do we have three Gods?
Answer NO despite what other religions would have you believe Christians only have One God We see this a number of times in the bible
Isaiah 44:6
“This is what the LORD says— Israel’s King and Redeemer, the LORD Almighty: I am the first and I am the last; apart from me there is no God.
Isaiah 44:8
Do not tremble, do not be afraid. Did I not proclaim this and foretell it long ago? You are my witnesses. Is there any God besides me? No, there is no other Rock; I know not one.”
Both say there is no other besides him
Deuteronomy 4:35
35 You were shown these things so that you might know that the LORD is God; besides him there is no other.
Deuteronomy 4:39
Acknowledge and take to heart this day that the LORD is God in heaven above and on the earth below. There is no other.
Deuteronomy 6:4
4 Hear, O Israel: The LORD our God, the LORD is one
2 Samuel 7:22
“How great you are, O Sovereign LORD! There is no one like you, and there is no God but you, as we have heard with our own ears.
Psalm 86:10
For you are great and do marvelous deeds; you alone are God
Mark 12:29
“The most important one,” answered Jesus, “is this: ‘Hear, O Israel, the Lord our God, the Lord is one.”
Paul Throughout in Ephesians 4:5-6 and in I Corinthians 8:6 that there is “one God”
All of these scripture talk about the same thing that we serve one God
2nd Is Jesus God?
Answer yes he is. It is all over the new testament lets start with
John 1:1-14
In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of men. The light shines in the darkness, but the darkness has not understood it.
There came a man who was sent from God; his name was John. He came as a witness to testify concerning that light, so that through him all men might believe. He himself was not the light; he came only as a witness to the light. The true light that gives light to every man was coming into the world. He was in the world, and though the world was made through him, the world did not recognize him. He came to that which was his own, but his own did not receive him. Yet to all who received him, to those who believed in his name, he gave the right to become children of God— children born not of natural descent, nor of human decision or a husband’s will, but born of God.
The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the One and Only, who came from the Father, full of grace and truth.
Next lets look at
John 8:58 were Jesus said that he was the “I am”
Jesus said in John 10:30 “I and the Father are one.”
Thomas called Jesus God in John20:28
These were just a few you can also look at Luke 5:20-21,Colossians 1:16-17, Titus 2:13, Hebrews 1:5-8, Revelation 1:8 and 22:13, and Isaiah 9:6-7
3rd What were some of the things Jesus said
He said to worship only God in Matthew 4:10. He accept worship as God in Matthew 14:31-33. God says worship Jesus in Hebrews 1:6. Jesus said in John 8:24 we would die in our sins if we do not belive that he was who he claim to be.
4th Is the Holy Spirit God
Answer Yes The bible says the holy spirit has all the characteristics that God has there for he is God
Hebrews 9:14 says the holy spirit is Eternal we learn that the Holy Spirit is Omnipresentin Psalm 139:7-10
The Holy Spirit is Omnipotent says Luke 1:35, John 14:26 says the Holy Spirit is Omniscient. Acts 5:3- 4 says that the holy Spirit is God
In closing here is some other prof for the Trinity
In the old Testament the Hebrew for God is Elohim, which means more then two.
Genesis 1:26 says Let us make man in our image,
Also read Matthew 3:16 Matthew 28:19 and II Corinthians 13:14
