Fidelity to the monastic way of life is closely related to zeal for the Kingdom of God and for the salvation of the whole human race. Monks bear this apostolic concern in their hearts. It is the contemplative life itself that is their way of participating in the mission of Christ and his Church and of being part of the local church. This is why they cannot be called upon to render assistance in the various pastoral ministries or in any external activity, no matter how urgent the needs of the active apostolate.
