The 52nd annual Dunker Church Service will be held on Sunday, September 18 at 3:00 pm in the old Dunker meetinghouse on the Antietam Battlefield. This service is held each year on the Sunday closest to the anniversary of the Battle of Antietam. The service commemorates the peace witness of the German Baptist Brethren families who worshiped there and offered their building as an improvised hospital. The speaker will be Carl Bowman, professor of sociology at the University of Virginia and formerly Bridgewater College. He has done extensive research on the social practices of the Brethren in the 19th and 20th Centuries.  The service will be typical of the simple worship style of Anabaptists in the 1860’s with a capella four-part singing. The service is sponsored by the churches of the Mid-Atlantic Church of the Brethren District. The public is invited. (Persons are encouraged to be vaccinated against Covid-19 and wear a mask.)
