3 John 1:5
Dear friend, you are faithful in what you are doing for the brothers and sisters, even though they are strangers to you — Gaius's hospitality to itinerant brothers represents costly, sacrificial love extended to those without kinship claims or social ties, thereby manifesting the gospel's radical redefinition of community. The characterization of guests as 'strangers' (xenous) emphasizes that Gaius's welcome transcends natural affinity or mutual benefit, placing his actions squarely within Christian ethics of neighbor-love and eschatological hospitality. His fidelity ('pisteuseis,' literally 'you believe') is expressed not in doctrine but in action, suggesting that faith demonstrates itself through works.
