Middernachtmis

Middernachtmis (Dutch for midnight Mass) is a liturgical service of the Catholic Church traditionally celebrated around midnight on Christmas Eve to commemorate the Nativity of Jesus. The term is used primarily in Dutch-speaking communities in the Netherlands and Belgium, where the service is a recognizable part of Christmas observance.

Historically, the practice stems from the Christmas Vigil and the belief that the incarnation occurred at night. The liturgy typically includes Scripture readings about the Nativity, a homily, the celebration of the Eucharist, and the singing of carols. Churches are often decorated with nativity scenes, and some communities incorporate processions or additional prayers. While midnight was once the standard start time, many parishes now hold the Mass in the late evening, around 23:00, with some continuing to mark a true midnight hour.

Geographic and denominational scope varies. In the Dutch-speaking world, middernachtmis is commonly associated with Catholic parishes, though Lutheran and Anglican communities in the region may hold Christmas Eve services with different local customs. The term itself is most closely tied to Catholic practice, and other denominations may use different terms for their late Christmas Eve liturgies.

Contemporary practice reflects changing schedules and traditions. In some areas, the midnight Mass has shifted to earlier in the evening or to other Christmas Eve services, but the middernachtmis remains a traditional and culturally significant element of Christmas worship for many communities, preserving a sense of continuity with historic observances.
