More than fifty years ago, Saint Paul VI introduced the expression “dialogue of salvation” and he interpreted the mission of the Son in the world as an expression of an “appeal of love”. He added, though, that we are “free to respond to it or to reject it” (cf. Ecclesiam Suam, 75). From this perspective, the act of personal faith appears both free and liberating:it will be the point of departure for a gradual appropriation of the contents of the faith. So faith is not an element added to freedom as if from outside, but it fulfils the desire of conscience for truth, goodness and beauty, rediscovering them fully in Jesus. The witness of so many young martyrs past and present, echoed powerfully at the Synod, is the most convincing proof that faith sets us free in the face of the powers of this world, in the face of its injustices and even in the face of death.
