why is the trinity a necessary part of christianity? what parts

Christianity = Trinity
Arianism = No trinity
It's not that complicated. Christianity is partially defined by belief in the trinity and without it ceases to be Christian as we know it but something else.

The part where Jesus has authority to override God the Father's decisions.

when did this happen?

Has jesus ever overpowered God?

Didn't jesus simply convince God to reconsider ? Or use some of the power that was given to him by God but which God could overpower if he was so inclined?

it says that arianism is a type of christianity.

>it says that arianism is a type of christianity.
Than you answered your own question, OP. You can be a Christian and not believe in the trinity. Just the most popular forms of Christianity believe in the trinity.

You have the entirety of Replacement Theology, for starters.

>>2516967
are you saying that you can't say that christianity replaces judaism without the trinity?

I disagree.
You can say that jesus is the created son of God and he was sent to Earth and so as an agent of God, jews are meant to follow his instructions so jews should become christians and the way they follow their faith when they believe that jesus is not the son of god and do not listen to him is less valid than the way christians follow their faith.

Yes.

The problem with that is that God promises the Jews that their covenant will be eternal, no matter how badly they sin (Pretty much the entirety of Deuteronomy, chapter 4), and in fact specifically warns them not to listen to prophets and dreamers like Jesus who do miracles and tell them that the Covenant is to be abrogated. (Deuteronomy, chapter 13, either verses 2-6 or 1-5 depending on your bible's edition)

I'll need to investigate these claims myself but it seems to me that God is perfectly capable of changing his mind and sending a special part divine part human being (which is not God but was created by God) to tell humans what to do.

>>2517231

A corollary of that position is that God lied to who knows how many millions of people about something like the salvation of your eternal soul. That doesn't exactly fit with a Good or Just deity.

Besides, isn't that what prophets are for? And in fact, assuming your logic, what makes Jesus different from any other prophet other than having a partially divine nature?

>>2517231
God knows what happens from the beginning.
Before God created the Garden of Eden and Made Adam and Eve, he already knew they would disobeyed Him. He knew Satan would win The Spiritual battle in Eden. He knew he would have to create a human Body to. Come our atonement at Calvary. His oneship In a Human body that he would name Jesus.
