The (Plymouth) Brethren, in the tradition of free-church Protestantism, have historically been adverse to practices such as the Christian year that they cannot justify with a direct appeal to Scripture. They have given minimal recognition to Christmas and Easter as Christian holidays and have observed these days more for their evangelistic potential than as a celebration of the lordship of Christ over time. The reason that since many unbelieving persons in North America still have some consciousness of the importance of going to church on these holidays, Christmas and Easter are opportune times to preach the gospel themes of Incarnation and Crucifixion/Resurrection to a larger-than-normal audience. But, for the most part, the Christian year is completely ignored by the Brethren.
Plymouth Brethren worship is characterized by a commitment to austerity and simplicity. Music in worship has traditionally been limited to unaccompanied hymn singing. Musical and artistic creativity is most prevalent in Open Brethren churches in worship services other than the breaking of bread service. In some cases, instrumental accompaniment, contemporary music, and dramatic presentations of portions of Scripture are now used.
