You cannot be a Christian and not believe that Jesus is God. One of the earliest teachings passed down to use from the early church. It is a central doctrine of Christianity and all the church fathers believed in the trinity. When Paul told the lame man to walk watch what happened...
11 When the crowd saw what Paul had done, they shouted in the Lycaonian language, “The gods have come down to us in human form!”
13 The priest of Zeus, whose temple was just outside the city, brought bulls and wreaths to the city gates because he and the crowd wanted to offer sacrifices to them.
Acts 14 But when the apostles Barnabas and Paul heard of this, they tore their clothes and rushed out into the crowd, shouting: 15 “Friends, why are you doing this? We too are only human, like you. We are bringing you good news, telling you to turn from these worthless things to the living God, who made the heavens and the earth and the sea and everything in them. 16 In the past, he let all nations go their own way. 17 Yet he has not left himself without testimony: He has shown kindness by giving you rain from heaven and crops in their seasons; he provides you with plenty of food and fills your hearts with joy.”
When Paul and Barnabas saw they were being worshiped as gods they tore their clothes!! But Jesus accepted worship, why, because He is God!
Peter walked with Jesus on the water and began to sink. Jesus saves him and they get back in the boat and what happens?
32 And when they climbed into the boat, the wind died down. 33 Then those who were in the boat worshiped him, saying, “Truly you are the Son of God.”
According to John in the book of Revelation, the angel that he started worshiping also refused to accept divine obeisance. The angel insisted that John stop and said, “Do not do it! I am a fellow servant with you and with your brothers who hold to the testimony of Jesus. Worship God”
Jesus accepted worship, He claimed to be God. Titus 2:13 (NIV) declares that Jesus Christ is God, “We wait for the blessed hope-the glorious appearing of our great God and Savior, Jesus Christ.”
The Jews understood Jesus was claiming to be God, that is why the high priests sought to kill Him and told Him so.
No, one of the earliest and most fundamental doctrines of Christianity has been the trinity. Unless you believe Jesus is God you are believing heresy and putting your soul in danger.
