Evangelii Gaudium §134

134. Universities are outstanding environments for articulating and developing this evangelizing commitment in an interdisciplinary and integrated way. Catholic schools, which always strive to join their work of education with the explicit proclamation of the Gospel, are a most valuable resource for the evangelization of culture, even in those countries and cities where hostile situations challenge us to greater creativity in our search for suitable methods.[111]
