Evangelii Gaudium §168

168. As for the moral component of catechesis, which promotes growth in fidelity to the Gospel way of life, it is helpful to stress again and again the attractiveness and the ideal of a life of wisdom, self-fulfilment and enrichment. In the light of that positive message, our rejection of the evils which endanger that life can be better understood. Rather than experts in dire predictions, dour judges bent on rooting out every threat and deviation, we should appear as joyful messengers of challenging proposals, guardians of the goodness and beauty which shine forth in a life of fidelity to the Gospel.
