When nearly precise rabbinic parallels to stories and sayings in the Gospels exist, it may indicate that the Gospels are preserving traditions of the early Jesus movement and, perhaps, the historical Jesus.
The growing value placed on charity in the first century C.E. cannot be overstated. As a new sensitivity developed within Judaism that challenged the compensatory “blessings and curses” paradigm of the Hebrew Bible (cf. Deut. 28) as a basis to serve God, so there was a shifting emphasis towards altruistic love embodied in the Levitical commandment, “…and you shall love your neighbor as yourself (וְאָהַבְתָּ לְרֵעֲךָ כָּמוֹךָ אֲנִי יי; Lev. 19:18).”
What is the relationship between the preaching of Jonah and putting a lamp on a lampstand? The prophet Jonah in classical Jewish thought calls to mind repentance. In Rabbinic literature we read that many prophets were sent to Jerusalem and the people did not listen, but to Nineveh one prophet was sent, and the people repented.
Some of the things Jesus emphasized in his teachings stand as strong warnings to those who belong to the community of faith. Jesus made statements about not lapsing into prideful judgmentalism, and becoming centripetal in one’s thinking. Jesus taught that our attitude toward other people—outsiders, even sinners—must be like God’s.
