He who through virtue and spiritual knowledge has brought his body into harmony with his soul has become a harp, a flute and a temple of God. He has become a harp by preserving the harmony of the virtues
Maximos the Confessor deploys the harp as a precise theological metaphor for the soul’s integration of virtue, distinguishing it from the flute (inspired contemplation) and the temple (indwelling Logos).
