Titus Flavius Clemens (c.150 – c. 215), known as Clement of Alexandria, was a Christian theologian who taught at the Catechetical School of Alexandria. A convert to Christianity, he was an educated man who was familiar with classical Greek philosophy and literature. Among his pupils were Origen and Alexander of Jerusalem. Clement is regarded as a Church Father, like Origen. He is venerated as a saint.
HOW TO CONDUCT OURSELVES AT FEASTS
The Spirit, distinguishing from such revelry 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 Loan,” because He cares for every breathing thing which He hath made. For man is truly a pacific instrument; while other instruments, if you investigate, you will find to be warlike, inflaming to lusts, or kindling up amours, or rousing wrath.
In their wars, therefore, the Etruscans use the trumpet, the Arcadians the pipe, the Sicilians the pectides, the Cretans the lyre, the Lacedaemonians the flute, the Thracians the horn, the Egyptians the drum, and the Arabians the cymbal. The one instrument of peace, the Word alone by which we honor God, is what we employ. We no longer employ the ancient psaltery, and trumpet, and timbrel, and flute, which those expert in war and contemners of the fear of God were wont to make use of also in the choruses at their festive assemblies; that by such strains they might raise their dejected minds.
