Strong parallel. They put Jesus as created and lower than Jehovah. His son.
Your quote "In Scripture, Jehovah always is represented as a singular masculine Superior, Yeshua is always described as His Offspring or subordinate, and the Spirit something else."
I don't see a whole lot of difference.
Jesus is named "the everlasting Father" and Jehovah calls him "O GOD" in Hebrews.
He has been exulted to the highest place ....ABOVE THE FATHER.
It pleases the Father that the son is exalted.
Jesus returned to the right hand of the Father. The Father is still on the throne. Jesus said not to pray to anyone but the Father, and ask in His (Jesus/Yeshua’s) Name. If Christ is equal why wouldn’t we just ask Him? Christ claimed that the Father possessed knowledge that He/Himself did not have. The word God used in the New Testament is theos. It just means devine. People think it means the Heavenly, Self-Existing, God of gods. It doesn’t. It just means devine. The same word is used wherever god (little g) is used. I’m not adding to scripture like most people do. I’m just reading what it says. The word for Spirit, pneuma is used several times not always describing the same thing. I admit in John 14 He is referring to a “person” but in John 3, He is not. As well in Galatians 5, walking in the Spirit refers to not a man but an energetic presence that fills the universe bringing order and structure. It’s a wavelength that we become sensitive to when we no longer harbour guilt, and do not seek to please the flesh. This is what some have described as enlightenment. I think it is along these wavelengths the Father can communicate with us. This is why we need forgiveness, to eliminate guilt. This is why we must forgive others, so their guilt doesn’t prevent them from hearing the Father. Obviously those views aren’t Biblically attained, however I didn’t just pull them out of my butt.
