Trying to answer the challenges proposed by the Laudato si’ encyclical letter and its proposed “integral ecology,” this essay deals with the possible interactions between ecotheology, ecophenomenology, and cultural anthropology, outlining an interdisciplinary approach to Incarnation. In the first part, the core ideas of the aforementioned encyclical are discussed. In the second part, ecotheology is discussed as an answer to the critiques that see in Christianism a hindrance against a deeper ecological thought. The third part discusses ecophenomenology, while proposing to integrate within the debate some new theoretical proposals. The fourth part discusses how to “cross the Rubicon” between ecotheology and ecophenomenology, while also describing both limits and opportunities for such crossings. In the conclusions, some ideas for further research are proposed, in the sense of a layered theory of Incarnation.
