The night sky, previously dark, was suddenly aglow with an astonishing brightness, revealing a multitude of heavenly beings, while a magnificent angelic hymn resonated across the tranquil earth, proclaiming the dawn of a significant chapter in human history: “Glory to God in the highest, and on earth peace, goodwill toward men.” In the heavenly realms, a majestic divine service unfolded, akin to ceremonies held in the Jerusalem temple. When the offering was placed upon the altar, the sound of sacred music rose in three distinct waves, marked by the resonating silver trumpet of the priests, echoing the continuous refrain of the "Trisagion." The angelic hymn mirrored this structure, comprising three phrases that embraced the full spectrum of existence—heaven, earth, and the human spirit. Throughout the chronicle of the Old Testament, there was but one other occasion when a mortal was graced with the heavenly song. It was when the prophet Isaiah, in a profound vision, witnessed the glory of the Lord of hosts, as 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)! At that moment, the very thresholds trembled at their powerful declarations, and the heart of Isaiah was overtaken with fear. In contrast, the angelic proclamation that reached the shepherds filled their hearts with bliss, joy, and serenity.
