Evangelii Gaudium §42

42. All of this has great relevance for the preaching of the Gospel, if we are really concerned to make its beauty more clearly recognized and accepted by all. Of course, we will never be able to make the Church’s teachings easily understood or readily appreciated by everyone. Faith always remains something of a cross; it retains a certain obscurity which does not detract from the firmness of its assent. Some things are understood and appreciated only from the standpoint of this assent, which is a sister to love, beyond the range of clear reasons and arguments. We need to remember that all religious teaching ultimately has to be reflected in the teacher’s way of life, which awakens the assent of the heart by its nearness, love and witness.
