40. Gnosticism is one of the most sinister ideologies because, while unduly exalting knowledge or a specific experience, it considers its own vision of reality to be perfect. Thus, perhaps without even realizing it, this ideology feeds on itself and becomes even more myopic. It can become all the more illusory when it masks itself as a disembodied spirituality. For gnosticism “by its very nature seeks to domesticate the mystery”, [Cf. Letter to the Grand Chancellor of the Pontifical Catholic University of Argentina for the Centenary of the Founding of the Faculty of Theology (3 March 2015)] whether the mystery of God and his grace, or the mystery of others’ lives.
