injury upon the whole

“… there is no sin in thought, or word, or deed, no matter how personal or secret, that does not inflict injury upon the whole fellowship. … We are members of a body, not only when we choose to be, but in our whole existence. Every member serves the whole body, either to its health or to its destruction.”

Life Together by Dietrich Bonhoeffer (Harper & Row, 1954), p.89.
