A noun meaning godliness, piety, or religious devotion. It refers to a comprehensive, well-directed reverence toward God that expresses itself in both worship and life. Eusebeia is the Greek word that comes closest to the English 'godliness' — an integrated posture of reverencing God and acting accordingly in every sphere of life.
Eusebeia is one of the key virtue terms in the Pastoral Epistles. Paul tells Timothy to train himself for godliness (1 Timothy 4:7-8) and declares that godliness with contentment is great gain (1 Timothy 6:6). The 'mystery of godliness' in 1 Timothy 3:16 refers to Christ himself — the source and substance of all true godliness. Crucially, 2 Timothy 3:5 warns of those who have a form of godliness but deny its power — religion without transformation. True eusebeia is not religious performance but life shaped by genuine encounter with the living God.
