I've noticed on RF there are a lot of heretical (that's the technical term) Christians who disbelieve in the Trinity.
Why?
We've had the creeds since Late Antiquity (Apostolic, Nicaean, Athanasian) and they all include the Trinity, especially the latter, which is all about it. These creeds are regularly read in churches and have been for hundreds of years. If the Trinity were so easily disproven, why would it have held out and been accepted by the orthodox Christians? Why spend so much time fighting the Arians? And why, I'm sorry to ask, is it almost always Protestants? Do you think you know something that everybody in the early orthodox Church failed to grasp?
Why is there so much of this around lately? How do you explain how Jesus is God without the Trinity?
How do you explain the worship of Christ?
And why is it treated in such a light manner?
John 17:3: And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent. (God is the only true God and Jesus was sent by God, disproving that Jesus is one of the 3 persons inside of God as in trinity or if he is God in flesh)
John 5:30: I can of Myself do nothing. As I hear, I judge; and My judgment is righteous, because I do not seek My own will but the will of the Father who sent Me. (here Jesus was saying he could not do anything on his own, how can a god not being able to do anything of his own? Jesus was also saying that he was sent by God and he was doing what God wanted him to do, a god obeying his god?! If Jesus was god in flesh then why is he saying he was sent by God? The Old Testament says God is one)
Mark 10:18: So Jesus said to him, “Why do you call Me good? No one is good but One, that is, God. (here Jesus was saying that he was not good because the only one who is good is God meaning he is not God or part of the God as in trinity because trinity says all 3 persons in God are equal, you can’t have one of the 3 persons in trinity, meaning Jesus, denying to be good/God, so this verse disproves that Jesus was god in flesh and it also disproves trinity)
John 20:17: Jesus said to her, “Do not cling to Me, for I have not yet ascended to My Father; but go to My brethren and say to them, ‘I am ascending to My Father and your Father, and to My God and your God.’" (here Jesus was saying he was going back to his father and their father so the term father is a symbolic term meaning a provider as a father provides. If Jesus is the son of God then he wouldn’t have said: “.. to my father and your father…”, he would have said: .. to my father. Also Jesus told his disciples; ..” my God and your God…” If Jesus was God in flesh or part of God as in trinity then he wouldn’t have said “…my God…” . How can a god have a god? Trinity states that all 3
persons in God are supposed to be equal existing in one God. Then none of the persons in trinity is god of the other two persons in trinity because then there would be more than one god, but God clearly says in The Bible that He is One God, so when Jesus said: " ….I am ascending to my God..." that disproves trinity and the idea that he is God in flesh because if he is God and he was going to his God then there would be 2 Gods, but There are clear verses in The Old Testament saying there is only one God. See the following verses in The Old Testament:
Chronicles 17:20 - There is none like you, O LORD, and there is no God besides you, according to all that we have heard with our ears”
Deuteronomy 6:4 - “Hear, O Israel: The LORD our God is one LORD
Isaiah 45:5 - I am the LORD, and there is no other; There is no God besides Me. I will gird you, though you have not known Me,
Isaiah 42:8 - I am the LORD, that is My name; And My glory I will not give to another, Nor My praise to carved images.
Isaiah 16:9 - Remember the former things of old, For I am God, and there is no other; I am God, and there is none like Me,
Deuteronomy 4:35 - To you it was shown, that you might know that the LORD Himself is God; there is none other besides Him.
Deuteronomy 32:39 ‘Now see that I, even I, am He, And there is no God besides Me; I kill and I make alive; I wound and I heal; Nor is there any who can deliver from My hand.
Some say God didn't want to tell the Jews at the time of Moses that He was made of 3 persons (as in trinity) because God wanted to gradually tell His creation later at the time of Jesus and onward that He was One God but made of 3 persons (Trinity).
The answer is: Even if God told the Jews at the time of Moses that He was made of 5 persons in one God, Jews would have believed Him because of the miracles they saw, so there was no reason for God not to reveal to the Jews His true nature in The Old Testament.
Also, God does not change and He does not lie as we can see in the Old Testament verses below:
Numbers 23:19 - God is not man, that he should lie, or a son of man, that he should change his mind. Has he said, and will he not do it? Or has he spoken, and will he not fulfill it?
Malachi 3:6 - For I the Lord do not change; therefore you, O children of Jacob, are not consumed.
