Direct Answer Based on the transcript, Christians should speak in terms of “fleshly Israel” and the “Israel of God” (believing Jews and Gentiles), recognizing a real shift of blessing to those who receive Christ, while remembering Paul’s point is about God’s freedom and justice—not about boasting. The lesson itself strongly describes Jewish rejection, so the main restraint implied is to keep the focus on God’s call and character rather than contempt for ethnic Jews.
