“For Luke the law remains the law given to Israel on Sinai, in the strict meaning of the word, the law of Israel. And Luke is concerned about the law because it is Israel’s law. Certainly Moses is a prophet as well (Acts 3:22; 7:37), but he is primarily associated with the law. It is significant that Luke is most concerned about the ritual and ceremonial aspects of the law. The law is to him not essentially the moral law, but the mark of distinction between Jews and non-Jews. The law is the sign of Israel as the people of God, which is evident from Luke’s overall perspective and from individual passages.”
