I've answered this type of question before.
I believe in Jesus' virgin birth, his life and miracles, his trials, persecutions and crucifixion, his burial and resurrection, and his ascension to the Father. I don't have to believe in a man made Trinity that took about 250 years to develop.
The history of the doctrine is clear.
1. Jesus became God in AD325 at the council of Nicaea.
2. The holy spirit became God in AD381 at the council of Constantinople.
3. Several arguments continued among the Bishops - over 100 of them. They could not resolve the multiple contradictions the Trinity or 'Nature of God' presented.
Examples are - Jesus saying the Father is Greater - that he doesn't know the day or hour of his return, - or that he can do nothing on his own. They overcame those contradictions in AD 451 under Pope Leo the Great. That's when Jesus acquired TWO NATURES which is the ultimate Trinitarian excuse for every contradiction.
Trinity is Christianity's most contentious doctrine. In my view, the concept of God is simple to understand. My experience is that the correct interpretation of anything is the most simple, logical, and least contradictory one. Both Pre-trib and Trinity are the most fabricated and contradictory doctrines in Christianity.
The facts...
1. Jesus became God in AD 325 at the council of Nicaea.
2. The holy spirit became God in AD 381 at the council of Constantinople.
151 years after Jesus became God, he acquired two natures at the Council of Chalcedon, which took place in 451 AD. This council defined the two natures of Christ as both fully divine and fully human, a doctrine known as the hypostatic union.
