The envious soul demands a goat, whereas the innocent yearns for the Lamb's sacrifice. This brother is termed the elder, as animosity quickly ages the spirit. He remains outside the home, for a heart filled with jealousy blocks the entrance to joy. Thus, he misses the sounds of singing and celebration—not the kind of dances that ignite lust or the raucous sounds of pipers, but the unified praise of the community celebrating the joy of the forgiven sinner.
Show me one who believes themselves righteous yet remains oblivious to their own faults, unable to help others with their minor issues (see Luke 6:41). They become indignant when forgiveness is offered to a contrite sinner who has earnestly sought mercy through tears. Their hearts are closed to the harmonious praise from the congregation! True harmony occurs when a psalm is sung within the Church, blending the voices of different generations and virtues like various strings on an instrument. The psalm is played, responses given, and ‘Amen’ expressed. This is the harmony that Paul understood when he declared, “I will sing with the spirit, I will also sing with the mind” (1 Cor. 14:15). This aligns with the message we aimed to illustrate in the parable we have considered.
We may not oppose the interpretation that these two brothers represent two nations: the younger brother symbolizing the Gentiles, and the elder brother reflecting Israel, who envies the younger because of the favor shown by their father. This mirrors the Jewish attitude when they grumbled about Christ dining with Gentiles (see Luke 5:30), thus demanding the sacrifice of an inferior goat. The Jew seeks a goat, while the Christian desires a Lamb; hence for the Jews, Barabbas was released (see Luke 23:18). Conversely, for us, the Lamb is sacrificed. They are left with the stench of their offenses, while we receive the sweet taste of forgiveness, full of hope. Anyone demanding a goat looks forward to Antichrist, for Christ is the fragrant offering (see Eph. 5:2).
The lament concerning the goat may signify that the Jews had lost the ancient ritual of sacrifice, realizing that no blood but Christ’s could redeem them, since the blood of prophets was incapable of salvation. The elder brother exhibits a lack of shame, resembling the Pharisee who proudly justified himself in prayer (see Luke 18:11). He believed he had never violated God's commandments and regarded himself as the epitome of obedience to the law. He reproached his brother for consuming their father’s wealth with immoral pursuits, failing to grasp that it was precisely for such individuals that it was proclaimed, “Tax collectors and sinners will enter the kingdom of God ahead of you” (Matt. 21:31).
The elder son remains outside the house not because he has been cast out, but due to his ignorance of God’s will regarding the inclusion of the Gentiles. He has transformed from son to servant, as a servant does not know his master’s business (see John 15:15). Once he understands, he is consumed by resentment, disturbed by the blessings of the Church, remaining outside. From his position outside, Israel hears the harmonious songs of praise and feels anger, unable to appreciate the gratitude expressed by those within, who are joyously singing together.
