While Christianity and Judiasm both are monotheistic religions and abrahamic faiths, they do have differences in terms of their beliefs and the idea of being saved. Jews believe that there is still a Messiah to come and while Jesus Christ was a good person they don't believe he is the true savior. Christians in contrast believe that Jesus is the Messiah and if you believe in him and repent for your sins then can you go to heaven. Judaism still follow the Jewish laws in Leviticus and can't eat pork while Christianity does not follow those laws except SDA or seventh day adventists. Christianity came after Judiasm.
