In North American Mennonite churches, styles of worship vary. Some Mennonite churches follow the liturgical calendar; others do not. Worship services may be similar to other Protestant services, with a worship leader and minister guiding worship. Lay leaders also tend to play important roles in leading Mennonite services. As a result of the emphasis on the importance of the community of believers, time for people to share experiences from their lives and stories for children are often incorporated into the worship service. Four-part singing has been a long-standing tradition in the Mennonite church, and for many years this was only a cappella singing. Now many congregations use organ, piano, drums or other instruments as accompaniment. Worship services reflect the racial and ethnic cultural context of the particular congregation.

With congregational singing playing such an important part in worship, many Mennonite churches use a song leader to lead the singing. Most Mennonite churches have Sunday school classes for both children and adults either before or after the morning worship. Mennonite churches seek to be friendly, welcoming places for visitors. Mennonites are known for taking the Bible seriously, especially the teachings of Jesus in the New Testament. The idea of following Jesus in everyday life, known as discipleship, is very important to them. This means they focus on things like community, nonviolence, and service to others. For example, many Mennonites oppose war and work towards creating a more just and peaceful world. Organizations like the Mennonite Central Committee (MCC) are good examples of Mennonites’ commitment to helping others around the globe.

Moderate Mennonites include the largest denominations, the Mennonite Brethren and the Mennonite Church. In most forms of worship and practice, they differ very little from many Protestant congregations. There is no special form of dress and no restrictions on use of technology. Worship styles vary greatly between different congregations. There is no formal liturgy; services typically consist of singing, scripture reading, prayer and a sermon. Some churches prefer hymns and choirs; others make use of contemporary Christian music with electronic instruments. Mennonite congregations are self-supporting and appoint their own ministers. The distinguishing characteristics of moderate Mennonite churches tend to be ones of emphasis rather than rule. There is an emphasis on peace, community and service.
