The Rule of Benedict established guidelines for monastic life in the sixth century C.E. The Rule ordered work and relationships, described decision-making processes and prescribed discipline and development for "the school of the Lord's service." Each monastery was, and is, a self-governing, economically-independent organization. These organizations survived through political and social turmoil, economic crises, and plague without abandoning the Rule and its organizational concepts. Modern Benedictines have altered their economic ventures, but continue to depend on the Rule for structuring their organizations. How has the Rule contributed to creating an "adaptable culture"? The Benedictine concepts of stability, fidelity, and obedience are discussed as precursors of organizational embeddedness, commitment, and preservation of the essential purpose. Hospitality is a Benedictine requirement that is often misunderstood to mean that they treat visitors well. In fact, hospitality ensures the organizations stay open to their environments, that they are open to diverse influences even if they appear hostile, and that all interactions are opportunities for learning. The balance of prayer and work creates a healthy yet economically productive organizational climate. In summary, the Rule structures an adaptable culture that leads to environmental sensitivity, organizational learning, tolerance, and openness to change while continuing to focus members' attention on the essential purpose.
