Paul begins by presenting the other side of the Gospel. The ‘proclamation’ is also a “denunciation.” The Gospel that reveals God’s saving justice also shows its opposition to everything that conflicts with it, revealing the “wrath of God.” He first speaks of the pagan world around him, to which he was sent to evangelize; then he addresses his own people, the Jews, to whom he has tirelessly proclaimed the Gospel, most of whom oppose and resist it. This is the introduction to the “Gospel of salvation”—the central theme of the Letter—and this presentation of “the wrath of God” can’t be understood without the proclamation of salvation that Paul is the messenger of. Let us remember that for the Apostle, “the wrath of God” is always expressed through his love.
