7 Therefore receive one another, just as Christ also received us, to the glory of God. 8Now I say that Jesus Christ has become a servant to the circumcision for the truth of God, to confirm the promises made to the fathers, 9 and that the Gentiles might glorify God for His mercy, as it is written: “For this reason I will confess to You among the Gentiles, and sing to Your name” (Romans 15:7–9, NKJV).
The gospel brings into one body people of all ethnic and cultural backgrounds. Whether Jew or Greek, slave or free, male or female, etc., “Christ is all and in all” (Col. 3:11; Gal. 3:28). He is our peace, reconciling us to God “in one body through the cross” (Eph. 2:14, 16). Therefore, outward, physical differences must not become barriers preventing us from receiving one another as Christ received us: Fully, complete, and to the glory of God (Rom. 15:7). Using Christ as our great example of pleasing others instead of ourselves, the inspired apostle summarizes the message of Romans 14. Like Christ, Paul urges Christians to sacrificially serve each other instead of pleasing ourselves over scruples of conscience (Rom. 15:1-3; 14:1-3, 13-18). Christ served the truth of God (Rom. 15:8). For the Jews, He did so by fulfilling the promises made to the fathers (Rom. 15:8; Acts 3:20-26). For the Gentiles, He did so as their (our) only means of mercy (Rom. 15:9-12). Surely, since Christ served us by serving the truth of God, we must “receive one another” without rancor, dispute, and division over matters that do not prevent God from receiving us (Rom. 14:3-5). This is not a defense of “agreeing to disagree” over doctrinal and moral issues (Gal. 1:6-9; 2 John 9-11). It is a pattern of how those who practice the truth of God receive one another to the glory of God (Rom. 15:7).
