1. The Instrument of God

“A beautiful breathing instrument of music the Lord made man, after His own image. And He Himself also, surely, who is the supramundane Wisdom, the celestial Word, is the all-harmonious, melodious, holy instrument of God. What, then, does this instrument— the Word of God, the Lord, the New Song— desire? To open the eyes of the blind, and unstop the ears of the deaf, and to lead the lame or the erring to righteousness, to exhibit God to the foolish, to put a stop to corruption, to conquer death, to reconcile disobedient children to their father. The instrument of God loves mankind. The Lord pities, instructs, exhorts, admonishes, saves, shields, and of His bounty promises us the kingdom of heaven as a reward for learning; and the only advantage He reaps is, that we are saved… This is the New Song, the manifestation of the Word that was in the beginning, and before the beginning.”

St Clement of Alexandria
Exhortation to the Heathen, ch. 1

2. The Universe as a Lyre

“For just as though some musician, having tuned a lyre, and by his art adjusted the high notes to the low, and the intermediate notes to the rest, were to produce a single tune as the result, so also the Wisdom of God, handling the Universe as a lyre, and adjusting things in the air to things on the earth, and things in the heaven to things in the air, and combining parts into wholes and moving them all by His beck and will, produces well and fittingly, as the result, the unity of the universe and of its order.”

St. Athanasius
Against the Heathen, ch. 42

3. Our Body the Organ – Our Nerves the Strings

“The Spirit, distinguishing from such revelry [of the pagans] the divine service, sings, “Praise Him with the sound of trumpet;” for with sound of trumpet He shall raise the dead. “Praise Him on the psaltery;” for the tongue is the psaltery of the Lord. “And praise Him on the lyre.” By the lyre is meant the mouth struck by the Spirit, as it were by a plectrum. “Praise with the timbrel and the dance,” refers to the Church meditating on the resurrection of the dead in the resounding skin. “Praise Him on the chords and organ.” Our body He calls an organ, and its nerves are the strings, by which it has received harmonious tension, and when struck by the Spirit, it gives forth human voices. “Praise Him on the clashing cymbals.” He calls the tongue the cymbal of the mouth, which resounds with the pulsation of the lips. Therefore He cried to humanity, “Let every breath praise the Lord,” because He cares for every breathing thing which He hath made. For man is truly a pacific instrument.”

St. Clement of Alexandria
The Instructor, Book II

4. Our Harmonious Music

“But the harmony [of the Holy Fathers] is broken neither by difference of periods nor by diversity of language; like the harp their strings are several and separate, but like the harp they make one harmonious music.”

Orthodoxus and Eranistes
Dialogue III
