"The word "sign" is a word tied to the sacramental nature of the Church: to say that the Church is, in all its being, in all its historical reality, a sign for the world, this has not yet been developed as far as it could be. In the same way, saying that the Church has the obligation to read the signs of the times, to be open to the history of humanity interpreting with wisdom all that human reality is, and discerning in it what can be a sign of the Kingdom of God."
