Sketching human existence from among four parables, the exercise of freedom is described as an effective disposition before the mystery of original alterity which precedes and involves human beings in their entirety. As the force that responds to the provocation of this instance, freedom dramatically generates an affective interpretation of the enigma of the origins (a moving gift or an intolerable imposition?) and the effective expectation of an ought-to-be so that life might be good. The recognition-of-being-recognised-as-son is presented, to conclude, as another manner of naming the realisation of freedom that is disposed to the bounty of the Origin of life (and of its Destiny), precisely because it is recognised as trustworthy. Indeed, the most elementary matter to be decided in the exercise of freedom is the grace of trusting in being loved (and the disgrace, the fear of not being loved). An extraordinary example of how one is a Son is the story, among us, of the liberty of Jesus of Nazareth.
