In 2009, in an address to Catholic religion teachers, Pope Benedict XVI drew upon St. Paul's example to offer some very helpful thoughts for religion teachers. A snippet:

The last Letters of his correspondence, the so-called "pastoral" Letters, are full of significant references to the social and civil life that Christ's disciples must keep clearly in mind. St Paul is a true "teacher" who has at heart both the salvation of the person in whom has been inculcated a mentality of faith, and the person's human and civil formation, so that the disciple of Christ may express to the full a free personality, a human life that is "complete and well prepared", which is also shown by attention for culture, professionalism and competence in the various fields of knowledge for the benefit of all. Consequently the religious dimension is not a superstructure, it is an integral part of the person from the very earliest infancy; it is fundamental openness to otherness and to the mystery that presides over every relationship and every encounter with human beings. The religious dimension makes the person more human. May your teaching always be able, like Paul's, to open students to this dimension of freedom and the full appreciation of man redeemed by Christ as he is in God's plan, thereby expressing true intellectual charity to countless children and their families.
