The Annual Christmas Carol Service, sung by the Harvard University Choir, is America’s oldest carol service. Program link: https://bit.ly/3ynATgg In 1910, the newly appointed University and Choirmaster, Archibald T. Davison, and Plummer Professor of Christian Morals, Edward C. Moore, devised the first annual Christmas Carol Service for Harvard University. The liturgy they prepared has remained virtually unchanged since: three lessons from scripture, interspersed with choral and congregational carols, beginning with “Adeste, fideles” sung in Latin. Over a century later, this service continues to be a cherished part of the festive season for the Harvard and Cambridge communities.
