Lutheran religious practices
Lutherans generally place great emphasis on a liturgical approach to worship services; music also forms a large part of a traditional Lutheran service. Lutheran hymns are sometimes known as chorales, and Luther himself composed hymns and hymn tunes, the most famous of which is "A Mighty Fortress is Our God" ("Ein feste Burg ist unser Gott"). Many Lutheran churches have active music ministries, including choirs, hand-bell choirs, children's choirs and sometimes carillon societies (to ring bells in a bell tower). Johann Sebastian Bach, a devout Lutheran, composed music for the Lutheran church.

Children's ministries are considered fundamental in most Lutheran churches. Almost all maintain Sunday Schools, and many host or maintain private nursery-schools, primary schools, regional high schools and universities. Lutheran pastors and staff are repeatedly reminded that most evangelism occurs within the church, with children.

Pastors usually teach in the common language of the parish. In the U.S., some congregations and synods traditionally taught in German or Norwegian, but this custom has been in significant decline since the early/middle 20th century.

Pastors almost always have substantial theological educations, including Greek and Hebrew so that they can refer directly to the canonical Christian scriptures in the original language. Lutheran pastors may marry and have families.

Lutheran ecumenism
Lutherans believe in the idea that there should be a single Christian church, and a single Christian faith. This belief is ingrained in the Lutheran confessions, and reflects the history of Lutheranism as a reform movement rather than a separatist movement.

For that reason, a number of modern Lutheran denominations, now largely separated from state control, are reaching out to other Lutheran denominations as well as other Christian denominations. However, more conservative varieties of Lutheran strive to maintain historical distinctiveness, emphasizing doctrinal purity over ecumenical outreach.

The largest organizations of Lutheran churches around the world are the Lutheran World Federation and the International Lutheran Council, which include the great majority of Lutheran denominations around the globe.
