What are two common key concepts between Christianity and judaism?

Both religions believe in the Torah Both religions are monotheistic

Explanation: Above all, Judaism and Christianity are monotheistic, so-called Abraham's religions. While the Jews have and respect the Old Testament, where the Torah is among others, they do not recognize the New Testament. In addition, the Jews also have a Talmud. Christians recognize the New Testament and Old Testament, and so does Torah. In addition, Christians acknowledge the records of the holy fathers of the Church. So it can be said that Christians and Jews share only the Old Testament.
The Jews do not believe that Christ is the Messiah, the Son of God, while the Christians believe in it, that is, the Christians believe in the Holy Trinity.
Christians visit the Churches, while the Jews visit the synagogues.
