Values based largely on the summarization of the moral law of God in the 10 commandments, which both Jews and Christians share, last I checked, further summarized in the two greatest commandments: You shall love the Lord your God with all your heart and with all your soul and with all your might, (Deuteronomy 6:5, summarizing commandments 1-4) and you shall love your neighbor as yourself (Leviticus 19:18, summarizing the last 6).

So, while the two faiths may not be theologically compatible, they are largely compatible when it comes to ethics/values.
