The author proposes some considerations about Liberation Theology in celebration of its 40 years of existence. At first, he highlights three features that justify the claim put forth by Latin-American Liberation Theology of presenting itself as "a new way of doing theology": 1) new relationship vis-a-vis the Praxis; 2) new perspective from which we can discern the challenges posed by the Praxis; 3) new methodology able to unite spirituality and theological method. In a second moment, Liberation Theology is recognized and presented as an authentic theologia crucis. This means that the cross of Jesus is accepted by Liberation Theology in a threefold manner: agnostical axis, epistemological principle and formal criteria. Finally, the author stresses the virtuous circle witnessed by Liberation Theology between the local and the global. Epistemologically, Liberation Theology is materially global and formally private. Historically, throughout its forty years, Liberation Theology has been revealed as a true "glocal" theology, witnessing a circular relationship between the particular and the universal.
