As Lutheran services are conducted in many different languages, cultures and countries, there are inevitably variations in expressions and styles of worship. Generally, however, Lutheran services are in the 'catholic' tradition, following the ancient liturgies and observing historic usage.
Music has always been an important part of Lutheran worship - services are often sung and instrumental music is common. There have been many great Lutheran composers who wrote prolifically for their churches - perhaps Bach and Mendelssohn are the best known. Lutherans celebrate Holy Communion regularly, believing that Christ is really present in his fullness in the bread and wine of the sacrament. Lutherans administer Holy Baptism to infants and adults, believing that God gives forgiveness of sins and faith through His word and the water used in this sacrament.
