The chief aim of this epistle text is to instruct those in official authority in the Church. Since Christians are under obligation to honor their pastors and teachers, they are admonished by the apostle to guard against the sin of vain-glory, that those in authority may not become proud nor misuse their office against unity in doctrine and in love, and that they may not despise or pass by the wounded and helpless, as the priest and Levite did. Lk 10, 31-32. Finally, Paul exhorts all diligently to do the good and thus serve everyone, as Christ also teaches in the Gospel (Mt. 6, 34) that everyone should do the work of each day and not be anxious about the future.
