Just as Protestantism was against the RCC but still is not Christian: the same applies to Unitarianism being contra trinitarism yet still not Christian!
Yes: Unitarianism is right about God not being Christ and Christ not being (a) God. Christ was created by God first before Creation Col 1:15, Proverbs 8:22-31. Thus Christ lived before Earth and Abraham existed and lived in God's Eternal Glory, John17:5, John1:2 thus also lived forever just as the angels and they could be called gods our godly. Yet there is 1 true God YHWH, a Spirit John4:24 and 1 Lord Christ, John17:3 1Cor8:6.
"Unity God" yet no Christ participating?!
Unitarianists are right about Christ not being God too. Christ was created before Creation (Col1:15) and lived with God in God's Eternal Glory before Creation (Prov8:22-31) before Earth and Abraham existed, John17:5, John1:2. Because God in His Almight and Wisdom knew the Original Sin would come to pass He created Christ before Creation and therefore Christ embodies that Wisdom of God:
"Christ the power of God, and the wisdom of God.", 1Cor1:24.
So Christ Yeshua is not the one and Eternal God YHWH but a creature. Yet he works in unity with God as we know from Prov8:30 and John10:32 and 37-38 saying:
"then I was beside Him, like a Master
Workman*, and I was daily His delight,
rejoicing before Him always", Prov8:30.
"Jesus answered them, “I have shown you many good works from the Father; for which of them are you going to stone me?”, John10:32
"If I am not doing the works of my Father, then do not believe me; but if I do them, even though you do not believe me, believe the works, that you may know and understand that the Father is in me and I am in the Father", John10:37-38.
*Strong 0525 Amown, skilled Architect, Workman
Christ doesn't say here he is God, but he refers to the WORKING UNITY between him and God YHWH, a Spirit John4:24. The Jews clearly don't understand that neither do Unitarians and common church trinitarians still talking about God, Christ and Spirits; even when they all agree on that God YHWH is One, Romans3:30, Deut6:4.
"God is a Spirit", John4:24
"For who among men knows the things of a man except the man’s spirit within him? So too, no one knows the things of God except the Spirit of God.", 1Cor2:11
God is His Own Spirit and even there are 7 Spirits of God (Rev5:6) - God YHWH is One, Romans3:30, Deut6:4.
So another problem of Unitarians is they cannot fathom how God is a Spirit Himself. Also they have no participating/linked Christ with God working in unity with God. They degrade Christ to an important witness, prophet and born Messiah only. They ignore he was created before Creation and that Christ is the co-creator linked to God, the assistant of God in that way in many roles as sent angel, sent Messiah, HighPriest of God and one day finally the Ambassador of God in Earth (Rev21:23: Christ as the Lamp of God on the throne).
"And the city has no need of sun or moon to shine on it, for the glory of God gives it light, and its lamp is the Lamb."
Unitarians however are no homogenic mass of believers. There are also those of Jewish roots clinging to the Jewish roots and Deut6:4 and either ignoring Christ completely or turning him into God completely like a kind of "mono-Binitarism" or just Binitarism. I wonder whether they understand their faith themselves at all?! And I usually see them ignoring the New Testament completely also...
Right faith, wrong ways nevertheless!
Of course Unitarianism is still a churchy antagonist of Babylon rooted churchy trinitarism where being a Christian has nothing to do with the worldly organized church organisation. And that pagan worldly churchy approach is still there:
The latinized church name Jesus is used; phonetic Latin out of phonetic Greek which is still not the true name of Christ! And John3:18 tells us the true name of Christ (Yeshua!) is needed or else one is condemned already!
Not praying to Christ, no relationship!
Also a little schizo to my opinion is that Unitarians kind of believe God is someone else than Christ yet refuse to build up a relationship with Christ too through praying directly to him, John14:13-14. In fact they are ignoring Christ that way also not praising him too (John5:23) and not worshipping him as Lord of God YHWH (Romans 10:9).
Still pagan trinitarian churchfeasts
Another problem: church Sunday keeping and church feasts that all originated from Babylonian paganism: the trinity sungodhead Baalder (holy sun-day), Easter (holy Easter) and Tammuz (holy winter solstice we now call Xmas) are unsuitable for Christians!
Positive prospects for the future?!
Yes: unlike the trinitarian people the Unitarian people have good possibilities. Obviously that's why they were persecuted severely. But they still have to address and untangle a lot of issues.
Above all they have to know God YHWH and Christ Yeshua, about how God created Christ first before Creation and about how Christ is linked to God YHWH Who is a Spirit. Christians work in Christ linked to the same God YHWH the same as Christ and angels do!
Secondly they need to establish a relationship with Christ too by speaking to him, but also asking him for forgiveness for ignoring him (John5:23); and asking the Father too! Christians only get access to God YHWH through Christ Yeshua only!
Thirdly they have to get rid of all (trinitarian) church ways, names and days/feasts. Instead they need to embrace God's Feasts & Days!
Last but not least
Being a Christian is a personal matter; being personally organized to go out as a person in Christ and in Spirit with the Spiritual Gifts thus actively growing in the Fruit of the Spirit. So this is not about the worldly organized churches, not about church activity turning into pagan church fruit and not about the broad church ways!
