19 That pastoral concern which ought to permeate thoroughly the entire training of the students also demands that they be diligently instructed in those matters which are particularly linked to the sacred ministry, especially in catechesis and preaching, in liturgical worship and the administration of the sacraments, in works of charity, in assisting the erring and the unbelieving, and in the other pastoral functions. They are to be carefully instructed in the art of directing souls, whereby they will be able to bring all the sons of the Church first of all to a fully conscious and apostolic Christian life and to the fulfillment of the duties of their state of life. Let them learn to help, with equal solicitude, religious men and women that they may persevere in the grace of their vocations and may make progress according to the spirit of their various Institutes. In general, those capabilities are to be developed in the students which especially contribute to dialogue with men, such as the ability to listen to others and to open their hearts and minds in the spirit of charity to the various circumstances and needs of men.
