In this Letter, the Bishop of Noto, Msgr. Antonio Staglianò, wants to explain his personal vision on the need to read again Rosmini’s works from a new perspective. Severino’s proposal or Heidegger’s proposal are perspectives that cannot give an acceptable solution to the relationship between reason and faith, philosophy and theology. Rosmini, conversely, has a still unknown perspective, which might be really decisive. The Bishop proposes that one consider a philosophy born “inside the bowels” of Christian theology. The thought of Rosmini (theologian-philosopher) can become fundamental for the challenges that Christianity and the Catholic Church, in particular, are facing today.
