Lutherans describe the church in terms of the worshiping assembly. “It is also taught that at all times there must be and remain one holy, Christian church. It is the assembly of all believers among whom the gospel is purely preached and the holy sacraments are administered according to the gospel.” (Augsburg Confession, 7)The Holy Spirit gathers the people of God around Jesus Christ present in the word of God and the sacraments, so that the Spirit may in turn send the people into the world to continue the gathering mission of God’s reign.Worship takes place in particular assemblies within particular contexts. Yet every assembly gathered by the Holy Spirit for worship is connected to the whole church. Worship unites the people of God in one time and place with the people of God in every time and every place.The Christian assembly also worships in the midst of an ever-changing world. And because the worship that constitutes the church is also the fundamental expression of the mission of God in the world, worship is regularly renewed in order to be both responsible and responsive to the world that the church is called to serve.
