A phenomenon as complex as the Fatima event stands itself as a challenge and demands theological reflection. From different perspectives, the core of the Message of Fatima reflects the very heart of revelation. It harmoniously reveals an authentic experience of Christian mystery at its most genuine and authentic. The symbolic nature of the language stands as a protest and a proposal in the face of particular circumstances in the world and in the Church. Fatima permits us to delve into the most radical logic of the revelation of the Triune God, whose love manifests itself as mercy in order to overcome, from within, the dramatic events of human history. The Little Shepherds bear witness of these designs of mercy announced to them.
