Evangelii Nuntiandi §18

18. For the Church, evangelizing means bringing the Good News into all the strata of humanity, and through its influence transforming humanity from within and making it new: "Now I am making the whole of creation new."[46] But there is no new humanity if there are not first of all new persons renewed by Baptism[47] and by lives lived according to the Gospel.[48] The purpose of evangelization is therefore precisely this interior change, and if it had to be expressed in one sentence the best way of stating it would be to say that the Church evangelizes when she seeks to convert,[49] solely through the divine power of the message she proclaims, both the personal and collective consciences of people, the activities in which they engage, and the lives and concrete milieu which are theirs.
