Ecclesiam Suam §67

⁶⁷ In fact no other course is open to Us in view of Our conviction that it is this kind of dialogue that will characterize Our apostolic ministry. From Our predecessors of the past century We have inherited a pastoral outlook and a pastoral approach. Our first teacher is that great and wise pope Leo XIII, who, like the prudent scribe in the Gospel, resembled a householder "who bringeth forth out of his treasure new things and old." (44) With all the dignity of the magisterial authority of the Holy See, he devoted himself wholeheartedly to finding a Christian solution to the problems of this modern age. Our other teachers are his successors, who, as you know, followed closely in his footsteps.
