Comment on Jewish concept of Messiah (Christ) is identical to our Christian concept of Anti-Messiah (Anti-Christ), brief comparison of Orthodox Judaism and Orthodox Christianity by mr Goss.
If you are looking for Christians that believe as the Jews do, truly in One God, the I am, then you are looking for Oneness Pentecostals. They attempt to correct the ecclesiastical teaching, non-biblical teaching, of the man-made doctrine of the Trinity. One cannot speak for all Oneness Pentecostals but in short Jesus was God Jehovah yet fully Man (grew tired, spoke as a man when crying our My God My God why hast though forsaken me, spoke as a man when he referred to ‘the Father “). He spoke as God (spoke as the one God manifest in the flesh, that fullness of God that dwelt in the man Christ Jesus) when he said he was “I am,” gave commandments and the like. Jesus is never referred to as God the Son in the bible. The man Christ Jesus “being put to death in the flesh” paved the way for salvation by the sinless blood spilt by the death of this man that the God (Jehovah)/Spirit in him raised up (raised the temple in 3 days). Belief that Jesus was both God and man, but in no fashion a separate God from Jehovah (the “I amâ€) in any way, is a core of their beliefs.
