There are many types of communites, the church is called together by the Spiriti and live in Christ for the praise and services of God
Apart from messages of Christ, baptism, communion - other churchly activities don't make sense
The church consists of people who in obedient faith have responded to God's call and by baptism have been added to His body
It is important to not allow compemtory or historial forms to take away from the simple essence of the church:
Church existes in each individual believer
The church does not cease to exist when not assembled as a group
The love of God from the Holy Spirit will drive them to fellowship
