Q: See Deuteronomy 6:4–How can God be Three as Christians teach, if The Shema clearly states that God is One?
A: Rather than being a problem for Christians, I have always viewed ‘The Shema’ (Deut.6:4) with awe and wonder, how well the mystery of the ‘Triune God’ can easily fit into this passage.
The point is, I believe that ‘Eloheynuw’ (plural) allows for the possibility of the Trinity rather than precluding it. Any Rabbi or Jewish teacher will argue against such an understanding, of coarse. However, see how well it really fits into the Christian understanding of God:
Our ‘Eloheynuw’ (pl) God is One.
Our ‘Triune’ (pl) God is One.
