The Divine Service (German: Gottesdienst) is a title given to the Eucharistic liturgy as used in the various Lutheran churches. It has its roots in the pre-Tridentine Mass as revised by Martin Luther in his Formula missae ("Form of the Mass") of 1523 and his Deutsche Messe ("German Mass") of 1526. It was further developed through the Kirchenordnungen ("church orders") of the sixteenth and seventeenth centuries that followed in Luther's tradition.
The term "Divine Service" is popularly used among the more conservative Lutheran churches and organizations of the United States and Canada. In the more progressive denominations, such as The Evangelical Lutheran Church in America, the terms "Holy Communion" or "the Eucharist" are much more commonly used.
In the parts of North American Lutheranism that use it, the term "Divine Service" supplants more usual English-speaking Lutheran names for the Mass: "The Service" or "The Holy Communion." The term is a calque of the German word Gottesdienst (literally "God-service" or "service of God"), the standard German word for worship.
As in the English phrase "service of God," the genitive in "Gottesdienst" is arguably ambiguous. It can be read as an objective genitive (service rendered to God) or a subjective genitive (God's "service" to people). While the objective genitive is etymologically more plausible, Lutheran writers frequently highlight the ambiguity and emphasize the subjective genitive. This is felt to reflect the belief, based on Lutheran doctrine regarding justification, that the main actor in the Divine Service is God himself and not man, and that in the most important aspect of evangelical worship God is the subject and we are the objects: that the Word and Sacrament are gifts that God gives to his people in their worship.
