Battle Baptists will play their national final at the home to Northampton Town Football Club.
Baptists discovered last Friday that their National Christian Trophy decider against St Cuthberts will take place at Sixfields Stadium on Sunday May 26 with a 6pm kick-off.
Admission will be £8 for adults and £4 for children/concessions. The club will be running at least two coaches from Battle on the day of the final. Anyone interested in booking seats on a coach should contact Battle Baptist Church Office on (01424) 774825.
Baptists booked their place in the final courtesy of a 2-1 victory away to Christchurch Bromley last month, while St Cuthberts got the better of fellow Liverpool-based side Focus Quest in the other last four tie.
Battle, whose achievements have far outweighed their expectations at the start of the prestigious knockout competition, previously eliminated Emmanuel Lightning (Croydon), Kings Sports (Hertfordshire) and Gold Hill Baptist (Buckinghamshire).
Baptists finished third in ADA East Sussex Football League Division Two and were just a point behind runners-up Icklesham Casuals. The club also fielded a second team in Division Five and a third side in Division Six.
