The Church journeys along the roads of history together with all of humanity. She lives in the world, and although not of the world (cf. Jn 17:14-16) she is called to serve the world according to her innermost vocation. This attitude, found also in the present document, is based on the deep conviction that just as it is important for the world to recognize the Church as a reality of history and a leaven in history, so too is it important for the Church to recognize what she has received from history and from the development of the human race¹⁹ 318*. The Second Vatican Council gave an eloquent demonstration of solidarity, respect and affection for the whole human family by engaging in dialogue with it about many problems, “bringing the light kindled from the Gospel and putting at the disposal of the human race the saving resources which the Church has received from her Founder under the promptings of the Holy Spirit. It is man himself who must be saved; it is human society which must be renewed”²⁰ 523*.
