I was going to say this about the trinitarians. Never in my life have I come across a mindset of a group of people who are incapable of understanding that God is One. They are the group of people who want to be right. Deut 6:4 Hear, O Israel: The LORD our God is one LORD. Now what part about "one" is so difficult to comprehend?
By the way, before anyone wants to use the word "elohim" as a plural for more than one, that word can be used either as a singular or plural. Research shows in a singular Elohim could be used as a plural of majesty.
Exod 7:1 And the LORD said unto Moses, See, I have made thee a god to Pharaoh: and Aaron thy brother shall be thy prophet.
The word "god" used here is the word elohim.
Another thing I have come across with trinitarians, they like to throw all sorts of verses that are at most implicit (implied instead of expressly stated, yet they ignore explicit verses (explicit meaning fully and clearly expressed, nothing implied). No matter how many implied verses you throw, even just one explicit statement overrides implied statements.
Now I am going to dissect the trinitarians belief right to the very core. Since you trinitarians believe Jesus is God, and God became a man (God meaning The Supreme Being in English) and accept that Jesus was crucified and killed, then going by that mindset, then you also accept that God got killed by his own creation, or God sacrificed himself to himself. This is what you trinitarians believe. Does this sound even logical? How does this even make sense?
By the clearly expressed verses you can see Jesus is monotheistic.
The Lord's Prayer, how did Jesus start the prayer? Our Father who art in heaven or did he say Our Father, Son and Holy Spirit in heaven?
In the verses when read in context in John 17.1-3 who did Jesus refer to the only true God? The Father or The Father, Son and Holy Spirit ?
Christians only believe in one God..the Triune God.
It is your claim that the Trinity teaches more than one god, and this is false. Christians are monotheists.
And, regarding the word "elohim", your argument's origins is Jewish concerning Elohim.
Additionally, regarding "oneness" mentioned in Deut 6:4, while Christians believe in monotheism, the word used for "one" is "echad" and can refer to complex unity, such as one cluster of grapes with more than one grape on the cluster. There is nothing in Deut 6:4 that prohibits the complex unity of the Triune God.
If you are familiar with the word "LORD" in the OT, there are many OT Scriptures quoted with regards to Christ in the NT, which are referring to YHVH, the one true God, in the OT. For instance, if you trace Romans 10:13 back to Joel 2:28-32, you will find that this NT quote is a reference to YHVH, thus proving Jesus is YHVH. Additionally, the Father is called Elohim in Isaiah 53:6.
So, we know both the Father and Son are identified with YHVH. John called the Holy Spirit another Comforter (with Jesus being the Comforter as the referent).
It really isn't too hard to see that Oneness people hold a faulty theology.
I have compared it to a sock-puppet theology....the three Persons are simply sock-puppets that the Oneness god dons.
The problem is that Scripture displays relationships between the three Persons of the one God.
Regarding Jesus, as a human being he died on the Cross. YHVH did not die; Jesus died. There is no problem with this if you understand the dual nature of Christ. He is both God and glorified man.
One of Jesus' roles was to display the perfect Adam to believers, to give his brothers the ideal model to follow. In this role, his humanity was important, and he did not go strutting about declaring his godhood at every moment. He came as a humble servant, showing us how to relate to God. However, he was still God, and accepted worship, as he did from the blind man and as he does in Revelation.
In addition, you would really have to ignore the types and shadows of Scripture to fail to realize the deity of Christ. For instance, Jesus reveals his body as the reality of the tabernacle and Temple in John 1-2. He "dwelt" or "tabernacled" with mankind showing the glory of the tabernacle. Who lived in the tabernacle or Temple? He was "God with Us" as the word Immanuel means.
So, if you're a Unitarian, you need to go back and study the tabernacle and Temple, and then read John in light of this.
And, to be honest with you, as an anti-Trinitarian in my younger days, I find it amusing how anti-Trinitarians think they are the ones who are enlightened and "Trinitarians" are a bunch of rubes who have blindly accepted teachings of Roman Catholicism. The reality is that Trinitarians are right, whether some are ignorant of the doctrine or not, and anti-Trinitarians are the ones who are dwelling in darkness. Especially if they deny Jesus is God..that's like the bottom of the barrel.
By the way, if someone denies Jesus is God, they are not even Christian. So, if that is the path you are heading down, you need to be aware that those who deny Jesus is God are not believers whatsoever. My understanding is that Oneness believers don't deny Jesus is God, so I am perplexed if you are defending Oneness theology.
