The members of the Kingdom of God should love one another under all circumstances.[VIII-35] They should bear one another’s burdens.[VIII-36] They should do good to all men, even to those who persecute. Above all, they should not recompense any man with evil for evil, or fail to feed their enemies if the latter hunger. Love is the law of God. Perfect love is more powerful than principalities and powers and even death.[VIII-37] Love conquers all evil. Love is more powerful than might. A practical, cosmopolitan brotherhood of man is one of the fundamental concepts of Paul’s teachings. Paul taught the organic unity of mankind. In the perfect Christian order each individual has a specific function to perform which is a part of the whole process. Paul compares this situation to the human body in which there are many organs, each performing its individual but correlated function.[VIII-38] No one liveth to himself, no one dieth to himself.[VIII-39] Every individual, even in dying, influences the social equilibrium and affects group progress. All individuals in the perfect Kingdom are co-laborers and co-operators. Whatever weakens one individual weakens society; whatever strengthens the individual strengthens society, providing that strength is used societarily. Another fundamental element in the social thought of Paul was his concept of sin. Sin is socially and individually destructive. The wages of sin--a generic term--is death. Paul made a long list of social sins, namely: covetousness, maliciousness, drunkenness, wantonness, dishonesty, fraud, stealing, fornication, murder. In nearly all his letters, Paul warned his followers against the evils which beset mankind. He urged people to beware of the appearance of doing evil. Paul’s rule of conduct was the Aristotelian mean: Be temperate in all things. On the other hand, Paul cited long lists of virtues. Love is continually urged. Temperance, meekness, gentleness, honesty, purity, and justice are repeatedly stressed. Paul’s description of a good man and bishop is the delineation of the character of a social citizen, who is temperate, a good husband, who is not mercenary nor covetous, and who ruleth well his household, with good reputation and character. In all Paul’s thought, righteous living was uppermost. Cheerful giving was commended. The strong should bear the infirmities of the weak, not only for the sake of the weak, but in order that the strong may not become self-centered. Paul taught a gospel of peace. He deprecated strife between individuals. He trusted in the operation of the law of love. Love will bring order out of confusion, and peace out of discord. The social Kingdom of God, motivated by love, moves orderly, harmoniously, and constructively.
