During services, members of a congregation entered the church and divided, with men seating on one side and women on the other. The pastor stood in front of the congregation at a small table with the Bible while he delivered a sermon. This was followed by the singing of several hymns, with no musical or instrumental accompaniment. Dunker services were typically about three to four hours long, as religion was the central element of a Dunker’s life. A Dunker church likewise reflected this degree of humility, adorned not with stained glass or steeples but by simple white walls and square windows. (These prominent white walls became a recognizable and easily seen landmark amidst the smoke and chaos of the battle in 1862.) Instead of rented pews, which signified status within the community, churchgoers chose to sit on common benches.

Communion is another service of the Church. The Dunker Communion Service consists, according to Scripture, of five parts: the Examination Service, the Footwashing, the Holy Kiss, the Love Feast and the Communion. The Examination Service was essentially a sermon, or several, reminding people directly if the occasion demanded, generally otherwise, of sin and need for forgiveness. Such might be the subject of the afternoon services ahead of Communion, but was part of the service that night. Implicit to receiving forgiveness from the Lord was the Scripture that we must forgive those who sinned against us. Some who were not ready to forgive another would refuse to attend, for kin and neighbors knew the problems between brethren (and sisters). To forestall this, previous to the Communion was a Deacon's Visitation to each member, to work out differences and feelings. The Examination Service concluded with beseeching the Lord for forgiveness.

The Foot Washing Service followed with the scripture that Jesus washed the Disciples feet, then commanded them to do as He had done to them. The eastern Brethren, and this likely included the Four Mile, practiced what is called the "double mode" of Foot washing. Here (men and women are seated separately and so wash their neighbor's feet) a basin of water is provided at the end of each table, with a long towel "with which he girded himself", long enough to wrap around the waist and hang down nearly to the floor, to be used for wiping. The feet are washed by gently running water over them, dipped up by hand out of the basin, or sometimes the feet are immersed in the water. Then the feet are dried with the towel, following which the brothers stand and exchange the holy kiss.
