Here’s the link to article VII: https://bookofconcord.org/augsburg-confession/of-the-church/
When read in conjunction with Article VIII, it becomes clear that the Augsburg Confession considers two different senses of “the Church.”
1) There is the Church Universal (or what we sometimes call “small c catholic”), which is comprised of all true believers in Christ.
2) There are local congregations, which consist of assemblies of believers in which “the Gospel is rightly taught and the Sacraments are rightly administered.
Technically, a person could be a member of the Church Universal without belonging to a local congregation. However, except in extreme situations where there are no other believers to fellowship with, it is abnormal for Christians to stay away from church. A person who refuses to be connected with a local body is in fact walking in disobedience to the Lord’s command and missing out on many blessings (Hebrews 10:25; Matthew 18:20; Colossians 3:16; Acts 2:42).
The second half of this article deals with the nature of unity and forms of worship in the church. Unity in the church comes from a common understanding of the Gospel and the means of grace. It is not necessary that rituals and traditions be identical.
