This noun denotes deity itself—the full essence and nature of divinity, not merely divine qualities. It differs from θειότης (divine nature in general) by emphasizing the totality of what makes God, God. Paul uses it in Colossians to declare that in Christ dwells all the fullness of the Godhead bodily. The term suggests not just divine attributes but the complete essence of deity concentrated in Christ. It appears in philosophical and theological discussions about the nature of divinity, emphasizing the comprehensive reality of divine being rather than scattered divine qualities.
