The church is…not a restricted religious community; if it were, the risen Christ would be merely the Lord of its cult. Nor is it a fellowship of like-minded people; in that case the Lord would only be there to give value to its mental attitude.
The church, with its cult and its attitude, is the earthly form of Christ’s lordship, which overcomes the world and the instrument of his liberation of that world.
from The Church in the Power of the Spirit
