About this church
Old Union Presbyterian Church is a PC(USA) congregation serving the Mars, Cranberry Township, and Evans City area since 1806. Traditional but informal worship is Christ-centered and Bible-based, with livestream access through Facebook, telephone dial-in, later YouTube recordings, and downloadable bulletins. The regular schedule is study groups for all ages at 10 a.m. and worship at 11. From May 24 through September 6, summer worship moves to 10 a.m. without Sunday School and alternates between the sanctuary and outdoor pavilion. Special joint and holiday services can replace that pattern, so the dated homepage calendar is essential for a specific Sunday.
The church began in the Reformed Presbyterian tradition, moved to its present site in 1839, and joined predecessor bodies that ultimately became the Presbyterian Church (USA). Its current building followed a 1905 fire, and a 2009 addition nearly doubled the ministry space. Daily video devotions stream Monday, Wednesday, and Friday at 2 p.m. Mission partners provide emergency food and housing help, literacy and job training, counseling, children’s beds, medical equipment for overseas hospitals, seminary education in Ghana, camps, and regional student outreach. A current mission team also participated in western North Carolina flood rebuilding. Public pages do not specify worship length, dress, parking, accessibility, nursery care, child check-in, Communion frequency, or livestream delay.
