The Chester County parish celebrates a 5 p.m. Mass on Sunday evenings, with many ministries performed by youths of the parish. Father Edward Hamilton, a retired priest, was the celebrant and homilist for Mass July 17, which was well attended even in the summertime. St. Isaac’s, which also celebrates Mass at 8 and 10:30 a.m. and noon on Sundays, is located at 50 West Walker Road and Valley Forge Road in Wayne. (Photos by Sarah Webb)
