This paper develops the framework of an integral ecology of the cross by weaving together principles from integral ecology, Christian theology, and phenomenology. Building upon the five principles outlined in The Variety of Integral Ecologies (particularly communion, subjectivity, and agency), I argue that the theological concept of kenosis (self-emptying) and the practice of ecological intentionality offer essential deepening for ecological ethics and spiritual engagement. Drawing from thinkers such as Thomas Berry, Leonardo Boff, Catherine Keller, Maurice Merleau-Ponty, and Edith Stein, the paper proposes a vision of ecological participation grounded in humility, interdependence, and sacramental presence. A case study of fire, examined through Indigenous stewardship practices and Christian sacramental symbolism, serves as a focal point for integrating liturgical, ecological, and metaphysical dimensions. Reimagining the cross not as a symbol of abstract salvation but as a paradigm of relational descent, the paper invites faith communities and scholars alike to consider new modes of ecological formation rooted in attention, vulnerability, and shared becoming. In an age of planetary crisis, an integral ecology of the cross offers a constructive theological and ethical response: one that honors suffering, performs peace beyond the human, and nurtures communion in the face of collapse.
