Kirchenzucht
The work of the Third Order is to engage laypeople to help in reform of church discipline. Its initial purpose was the preaching of penance; but under Dominican influences it leaned to the intellectual aspect of the Faith and based its message to the world on the exposition of the Creed; it was to reform Church discipline by the more widespread knowledge of the mysteries of faith. It also helped to defend the Church, and to develop the communion of prayer. The medieval ideal of Christ's Mystical Body which has captivated all spiritual-minded people implies a harmony of prayer. To achieve this end the contemplative and monastic orders were begun; and the Third Order of St. Dominic endeavours to link pious souls to this great throng of religious (Proctor, "The Dominican Tertiary's Daily Manual", London, 1900, 15–20).
