Unless you study the meanings of Memra and Logos, you will be suck with the idea that the Trinity is a necessary idea. Instead, one only need to understand Jesus as being the meaning, the purpose, the representation of God and the meaning, the purpose, the representation of humanity. Being representative is what matters and so, the salient belief is about whether or not all possible things to know about God are revealed in Christ and whether or not all possible things to know about humanity are revealed in Christ.
So to be Christian is to do no more than think Christ atones through the story his life “recapitulates”; not that of Adam’s which hides from God, but of a humanity which is, as John’s gospel describes Jesus, full of grace, infused with and indistinguishable from the “will of God” sacramentally.
One must wonder what on Earth is added or taken away from God or Christ if ontological oneness is declared, if one wondered at all. It neither clarifies nor illuminates either beyond the first century Greek meaning of Logos, or the Hebrew era prior where the idea of Memra emerged in the Targum.
