The most that one of Jewish faith can do - and some have gladly done it - is to say that Jesus was the greatest in the long succession of Jewish prophets. None can acknowledge that Jesus was the Messiah without becoming a Christian.

Latourette is drawing a boundary line between admiration and confession. He suggests that a Jew may, without abandoning Judaism, honor Jesus as an exceptional figure within Jewish religious history—at most, as a prophet in Israel’s line. But to affirm Jesus as “the Messiah” is, in his framing, not merely to offer high praise; it is to accept a specifically Christian claim about Jesus’ identity and salvific role. The statement reflects a common Christian historiographical approach: treating messiahship as the decisive doctrinal hinge that separates Judaism’s evaluation of Jesus from Christianity’s. It also implicitly comments on the limits of interfaith convergence when core theological definitions differ.
