On December 20, 2024, Christians celebrate St. Ambrose's Day, dedicated to Ambrose, the Bishop of Milan, a great theologian and the author of many church hymns. A popular saying goes: "Ambrose ended the festivities," as there are no major holidays until Christmas, celebrated on January 7, 2025. From this day on, preparations for Christmas begin. St. Ambrose was born into a wealthy Roman family in 340. His parents provided him with an excellent education, and by the age of 30, he became the governor of the Italian provinces of Liguria and Emilia. He is revered as one of the greatest theologians and the author of 30 church hymns. St. Ambrose also transformed church singing by introducing measured beats, proper rhythms, and diverse melodies.
