What Christianity thinks about the God of present day Judaism? I read here that most of the modern Christians believe in a Triune God and Consider Jesus to be  the God in trinity.  I was wondering What Christianity thinks about the God of present day Judaism , as they believe in a strictly monotheistic non trinitarian version of God as believed by the people at the time of Jesus and people before Jesus.

Is there a scope for accommodating the  monotheistic belief of Jews in God along with the trinitarian belief of Christians?
Fundamentally, Christians and Jews worship God the Father in similar fashion, but Christians (meaning Mainstream or Nicene aka Orthodox, Roman Catholic and Protestant Christianity) believe God to be larger than just that.  Nicene Christianity confesses that God the Father is "just" one person amongst three within the Godhead.  Muslims and Jews reject this.

While the Trinity is an offense to Muslims and Jews alike, it is nonetheless fundamental to the full understanding of the Godhead.  Christians believe that God is three distinct persons who are one.  This is a paradox. This is nonetheless true, for our limited understanding really precludes an obvious metaphor.

If we would focus on the distinct personalities of God as three individuals (which while technically the heresy of 'Tritheism' is nonetheless useful ) for the discussion here), then we could say:


The Christian understanding of God the Father is primarily (if not entirely) based on the same Scriptures as that of the Jews.  As such, when a Christian prays to God the Father, he could name him "Yahweh" and be perfectly consistent with the Jewish understanding.  (Indeed, it would also be very similiar to that of a Muslim).
Christians pray to God in the name of Jesus, the Son.  Christians fundamentally believe that the Son is God but that he is also Man.  He is not a separate God, but rather we perceive him in different ways.  When Jesus was incarnated, for example, he showed a certain distinction from God the Father (cf. Patripassianism), and yet there is no error in his saying, "I and the Father are one." He taught nothing that was not of accord with his Father.  Ironically, given your current name, He said "Nevertheless, Not my Will but Yours Be Done." In contrast, Jews reject any notion of the divinity of the Son, ergo, they do not agree with Christians in this aspect of God's true nature.
Christians believe that Holy Spirit "proceeds from the Father through the Son, and with the Son, He is worshipped and glorified."  I'd argue that in practice, most Christians really don't know what to do with the Holy Spirit - but they acknowledge that like the Son, he is God - though again, Jews (and Muslims) would disagree.


As such, the best answer is to say that Jews and Christians do worship the same God (specifically God the Father), but that Christians have a "fuller" (or "more complex" take your pick) understanding of his nature and how He relates to himself.
