Scout Finds the church service to be similar to her own except for few differences. Explain what these are.

From the text:

First Purchase was unceiled and unpainted within. Along its walls unlighted kerosene lamps hung on brass brackets; pine benches served as pews. Behind the rough oak pulpit a faded pink silk banner proclaimed God Is Love, the church’s only decoration except a rotogravure print of Hunt’s The Light of the World. There was no sign of piano, organ, hymn-books, church programs—the familiar ecclesiastical impedimenta we saw every Sunday. It was dim inside, with a damp coolness slowly dispelled by the gathering congregation. At each seat was a cheap cardboard fan bearing a garish Garden of Gethsemane, courtesy Tyndal’s Hardware Co.
