Human love produces human subjection, dependence, constraint; spiritual love creates freedom of the brethren under the Word. Human love breeds hothouse flowers; spiritual love creates the fruits that grow healthily in accord with God's good will in the rain and storm and sunshine of God's outdoors....
...life together under the Word will remain sound and healthy only where it does not form itself into a movement, an order, a society, a collegium pietatis, but rather where it understands itself as being a part of the one, holy cathloic, Christian Church, where it shares activly and passively in the sufferings and struggles and promise of the whole Church.

Dietrich Bonhoeffer. LIFE TOGETHER.
