The night sky, once filled with countless stars, burst forth with an ineffable brilliance, revealing a multitude of heavenly beings, as a triumphant angelic chorus echoed across the tranquil earth, proclaiming a new dawn in human history: "Glory to God in the highest, and on earth peace, goodwill toward men!" In the heavenly realms, a sacred divine service unfolded, akin to that celebrated in the temple of Jerusalem. As the offering was placed upon the altar, a celestial melody resonated in three distinct tones, marked by the sounding of silver trumpets, creating a constant echo of the sacred ‘Trisagion’. The angelic hymn mirrored this Trisagion in its threefold refrain, encompassing the divine, the earthly, and the human spirit. Throughout the entire account of the Old Testament, there exists a singular moment when a mortal was graced to hear the song of the heavenly realm. It was when the prophet Isaiah, in his exalted vision, beheld the glory of the Lord of hosts and the seraphim surrounding Him ceaselessly proclaimed, "Holy, Holy, Holy is the Lord of hosts! The whole earth is full of His glory" (Isaiah 6:1-3)! In that sacred moment, the thresholds trembled at the sound of their mighty utterances, and the heart of the prophet quaked in fear. Yet now, the angelic hymn that reached the ears of the humble shepherds filled their hearts with bliss, joy, and serenity.
