Sin, also for those who don't have faith, exists when one goes against one's conscience. To listen to and obey it means, in fact, to decide in face of what is perceived as good or evil. And on this decision pivots the goodness or malice of our action.
Pope FrancisThey (the consecrated) are men and woman who can awaken the world. Consecrated life is prophecy. God asks us to fly the nest and to be sent to the frontiers of the world, avoiding the temptation to 'domesticate' them. This is the most concrete way of imitating the Lord.
