φιλοξενία (literally 'love of strangers') denotes the virtue of welcoming guests and strangers into one's home and life. In the ancient Mediterranean world, where inns were scarce and travel dangerous, hospitality was both a moral obligation and a practical necessity for the spread of the gospel. Romans 12:13 urges believers to 'pursue hospitality' (τὴν φιλοξενίαν διώκοντες) as part of genuine Christian love. Hebrews 13:2 adds a striking motivation: 'Do not neglect hospitality to strangers, for by this some have entertained angels unawares'—evoking Abraham's welcome of the three visitors at Mamre.
