44 This sacred synod prescribes that in the revision of the code of canon law suitable laws be drawn up in keeping with the principles stated in this decree. Due consideration should also be given the observations made by the commissions and the council Fathers. This sacred synod also prescribes that general directories be prepared treating of the care of souls for the use of both bishops and pastors. Thus they will be provided with certain methods which will help them to discharge their own pastoral office with greater ease and effectiveness. There should be prepared also a particular directory concerning the pastoral care of special groups of the faithful as the different circumstances of individual nations or regions require. Another directory should be composed concerning the catechetical instruction of the Christian people; this directory will consider the fundamental principles of such instruction, its disposition and the composition of books on the subject. In preparing these directories, special attention should be given to the views which have been expressed both by the commissions and the council Fathers.
