11 With no less care, Venerable Brethren, would we have manifold cohorts of the Catholic Action polished or cultivated fitly by the Spiritual Exercises. With all our power, we desire to promote this Action; and we cease not, and will never cease, to commend it; because the co-operation of the laity with the apostolic hierarchy is exceedingly useful, not to say necessary. And, indeed, we can hardly find words to express the joy we experienced, when we learnt that special series of sacred meditations were established almost everywhere, for the cultivation of these pacific and strenuous soldiers of Christ and in particular for bands of young recruits. For while they crowd to this course, in order that they may be found more ready and more prompt to fight the battles of the Lord, they will find there not only the helps enabling them to express the form of the Christian life more perfectly in themselves, but may also, not rarely, receive in their hearts the secret voice of God, calling them to the sacred offices, and to work for the salvation of souls, and urging them on to the full exercise of the apostolate. This is, indeed, the glowing dawn of heavenly goods, and in a short time it will be followed and completed by a perfect day; if only the practice of the Spiritual Exercises is yet more widely extended and is propagated with prudence and wisdom among the various associations of Catholics and chiefly those of younger members.
