This could be interesting. I would like to know if Jews believe in a Trinitarian God.
I am a Messiannic Jew - a Jew who believe Jesus is the Messiah, and God Himself. The classic definition of Trinity would fit Jewish doctrine, but the idea that there are three gods, does not fit. So what is important in talking with or writing to a Jew is making sure you're communicating the right definition.
In short, I say I believe in the triune nature of God as one God, evident in three clearly distinct person - but the one and the same being.
Just to clarify. Are you telling us that a Messiannic Jew believes that the ONE God has THREE natures that are clearly evident in THREE clearly DISTINCT persons and these THREE poersons are ONE and the SAME beings - meaning they are ALL rolled into ONE?
Does your definition mean then that the Father is ALSO the son and ALSO the Holy Spirit?
