After having clarified that the bible is the ultimate authority for life, I will make my arguments based off of that. You will see a lot of scripture quoted because I believe that the bible is absolute truth.
I was really good at math until the end of the seventh grade. While finishing the seventh grade, we had to take a test to be in the advanced class for the eighth grade. But the teacher for this class was mean and everyone knew it. I had no desire to have her as a teacher so I intentionally failed this class and thus ended my math wizardry. My math skills were good enough to figure out a couple math problems that make no sense to me. Here are a few:
3 + Nothing = 1
I know that 1 does not equal 3 and 3 does not equal 1. That is easy to me.
That is why the concept of the trinity does not make sense to me.
How can three persons consist of one God?
The scriptures never even use the word trinity so why do people believe in this? Where did this idea begin?
Jesus’ words towards the end of the book of Matthew really shook many aspects of Christianity.
“All authority has been given to Me in heaven and on earth. 19“Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, 20teaching them to observe all that I commanded you; and lo, I am with you always, even to the end of the age.”
Jesus tells his disciples that he has been given authority, so he commands for them to baptize, not just in the father’s name or his name, but also in the name of the spirit.
Why would there be a baptism needed between the three of them? Jesus equated himself with God the father many times but to put the Holy Spirit among those two showed an equality that for some of us is surprising..
What’s the Old Testament Say?
The notion that ‘God is one’, is a large part of orthodox teaching that Jesus well understood as many Jews do today.
4“Hear, O Israel! The LORD is our God, the LORD is one!
So there is no doubt that there is one God. But his plurality is laid out throughout the scriptures. Here are several Old Testament scriptures that show plurality:
7“Come, let Us go down and there confuse their language, so that they will not understand one another’s speech.”
8Then I heard the voice of the Lord, saying, “Whom shall I send, and who will go for Us?” Then I said, “Here am I. Send me!”
26Then God said, “Let Us make man in Our image, according to Our likeness;
All 3 interact
In the New Testament, names are named even clearer. The usage shows the trinity at work at the same time. Showing that clearly all three coexist together at once. This defeats the thought of one God putting on three different mask at different times like the teachings of modolism.
Watch as all three interact…
16After being baptized, Jesus came up immediately from the water; and behold, the heavens were opened, and he saw the Spirit of God descending as a dove and lighting on Him, 17and behold, a voice out of the heavens said, “This is My beloved Son, in whom I am well-pleased.”
I Corinthians 12:4-6
4Now there are varieties of gifts, but the same Spirit. 5And there are varieties of ministries, and the same Lord. 6There are varieties of effects, but the same God who works all things in all persons.
II Corinthians 13:14
14The grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit, be with you all.
And one section of scripture where we see the work of each person in the trinity is in:
3Blessed be the God and Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly places in Christ, 4just as He chose us in Him before the foundation of the world, that we would be holy and blameless before Him. In love 5He predestined us to adoption as sons through Jesus Christ to Himself, according to the kind intention of His will, 6to the praise of the glory of His grace, which He freely bestowed on us in the Beloved. 7In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace 8which He lavished on us. In all wisdom and insight 9He made known to us the mystery of His will, according to His kind intention which He purposed in Him 10with a view to an administration suitable to the fullness of the times, that is, the summing up of all things in Christ, things in the heavens and things on the earth. In Him 11also we have obtained an inheritance, having been predestined according to His purpose who works all things after the counsel of His will, 12to the end that we who were the first to hope in Christ would be to the praise of His glory. 13In Him, you also, after listening to the message of truth, the gospel of your salvation—having also believed, you were sealed in Him with the Holy Spirit of promise, 14who is given as a pledge of our inheritance, with a view to the redemption of God’s own possession, to the praise of His glory.
The Holy Spirit seals our salvation.
The three are one.
So, Jesus was/is God?
Jesus explicitly lays out his divinity at many points of his ministry.
At one instance, the Jews were ready to kill him for his reference to Moses and Abraham.
56“Your father Abraham rejoiced to see My day, and he saw it and was glad.” 57So the Jews said to Him, “You are not yet fifty years old, and have You seen Abraham?” 58Jesus said to them, “Truly, truly, I say to you, before Abraham was born, I am.” 59Therefore they picked up stones to throw at Him, but Jesus hid Himself and went out of the temple.
When Jesus made this statement he elevated himself above Abraham and Moses declaring his eternal existence. He was indirectly quoting this famous passage…
13Then Moses said to God, “Behold, I am going to the sons of Israel, and I will say to them, ‘The God of your fathers has sent me to you.’ Now they may say to me, ‘What is His name?’ What shall I say to them?” 14God said to Moses, “I AM WHO I AM”; and He said,“Thus you shall say to the sons of Israel, ‘I AM has sent me to you.’”
Jesus’ reaction to the Jewish people in the temple displays a sense of divinity that he had and yet the people would never accept out of any man. The people picked up stones to kill him. That’s how serious it was and is.
The Bible lays out many other verses declaring his divinity:
Matthew 1:23, Isaiah 9:6, Isaiah 43:10-11, 2 Peter 1:1, John 1:1, 14, John 5:17-18, John 5:23, John 10:30-33, John 14:6-7, John 14:9-11, John 20:28, Acts 20:28, Philippians 2:5-7, 1 Timothy 3:16, Titus 2:13, Hebrews 1:8-9, 2 John 1:7, Revelation 1:8, Revelation 22:13,16, Colossians 1:16
For me, this is sufficient evidence to the mystery that will forever be debated and wrestled through. But this ultimately is important because this lays out the plan of our salvation. How can Jesus be the perfect sacrifice without being God? How can we function on this earth if the Holy Spirit that is inside of us is not God? Where does the strength come from for righteous living in our lives if the Holy Spirit is not God? While the spirit is here, who intercedes for us to the father?
All these questions are answered in the Trinity. Augustine said “to try to teach the Trinity you will lose your mind, to deny it you will lose your soul.” This is an important topic I hope you research and can enjoy.
And as a side plug, here is a poem I wrote about the Trinity.
