Selections From Bonhoeffer

How could one person pray the prayer of the fellowship without being steadied and upheld in prayer by the fellowship itself? At this very point, every word of criticism must be transformed into fervent intercession and brotherly help. Otherwise, how easily might a fellowship be broken asunder right here!
The free prayer in the common devotion should be the prayer of the fellowship and not that of the individual who is praying. It is his responsibility to pray for the fellowship. So he will have to share the daily life of the fellowship; he must know the cares, the needs, the joys and thanksgivings, the petitions and hopes of the others. Their work and everything they bring with them must not be unknown to him. He prays as a brother amongst brothers. It will require practice and watchfulness, if he is not to confuse his own heart with the heart of the fellowship, if he is really to be guided solely by his responsibility to pray for the fellowship.
