54. To you, Venerable Brethren, who labor so well in the Catholic Mission fields, is given the task of carefully putting these ideals and aims into practice. Ever keeping in mind special circumstances and varying conditions of time and place, take counsel together in your Bishops' meetings, in your synods and other gatherings, and strive by all possible means to establish those social welfare associations, organizations and societies which the present time and the modern mind seem to demand. Your pastoral office certainly requires this, lest the flock entrusted to you be led astray from the right path by passion and by new errors disguised as truth and justice. In this task let the missionaries who are your able cooperators, distinguish themselves in promoting this apostolate. Thus they can be sure that it will not be said to them: "The children of this world are wiser . . . than the children of light."⁴⁰ It will moreover prove helpful if they, whenever possible, gather round themselves qualified Catholic laymen of outstanding character and practical ability, who can take up and advance these works.
