Selections from the gospels will be read in the broad Scots dialect.
Carols and seasonal songs will be played on a bagpipe.
But not all of the annual Octorara Covenanter Presbyterian Church Foundation's Advent service will be a testament to the denomination's Scottish heritage.
This year's service will include a performance by a string ensemble from a local high school.
Members of the Solanco String Quartet will play a section of seasonal songs, including the Hornpipe in D, Eine Kleine Nachtmusik, and It Is Well Within My Soul.
The group's name is a misnomer - there are five members instead of four. Faith Redcay, Sarah Alexander, and Danielle Drumm play violins, Jenna Brown plays a viola, and Holland Hatch plays a cello.
"Technically, we're a quintet," Redcay said. "We've played together just this school year. Jenna, Holland, and I have played together longer."
The group plays mostly classical music but includes some songs from movies in its repertoire.
Now a junior in high school, Redcay has been playing a violin since she was in second grade. "I was at my sister's concert and I saw violins in the orchestra and thought that was cool," she said.
Their selections for this year's service include the third movement of Eine Kleine Nachtmusik and It Is Well With My Soul.
The Root Blossoms will also perform during the service. The group's selections include medleys of carols with Celtic tunes.
Donald Henderson will read selections from the Gospels of Luke and Matthew in the broad Scots dialect.
And, as befits a Scottish celebration, Thompson McConnell will play several carols on his bagpipe.
This year's service will be held at 3 p.m. on Sunday, December 1, at Middle Octorara Presbyterian Church 1199 Valley Rd., (Rt. 372).
The service is open to the public. Admission is free; an offering will be taken to help the foundation preserve and restore the historic Covenanter Church. That church is across Valley Rd. from Middle Octorara.
