Rio de Janeiro is a city in which human architecture and divine architecture live side by side. This reality becomes more evident at the top of Mount Corcovado, where nature, God s creation, and the statue of Christ the Redeemer, symbol of redemption, appear harmoniously, as if the monument could be understood almost as an extension of the mountain. The Christ of Corcovado is aesthetically beautiful and so full of meaning that it mixes with that famous view of nature by which the title wonderful city is confirmed. Originally conceived in the 19th century, the purpose of the monument was to communicate the heart of the Christian message in a universal language. After its inauguration in October 1931, the monument transcended the religious sphere, also representing the Brazilian culture to the world. In Occtober 2006, Mount Corcovado’s plateau was recognized as a Catholic sanctuary, a place of prayer and encounter, where people can be in harmony with God, with nature and with others. This thesis aims to translate the symbolism of the Sanctuary Christ the Redeemer into theological language, in the light of the encyclical letter Laudato Si and of integral ecology, to evangelize the culture, rich in its diverse manifestations, among which is presented the Corcovado monument itself, in the face of the challenges generated by the globalizing, consumerist and disposal mentality. In the first chapter we approach the Theology of the History of the Sanctuary Christ the Redeemer, seeking to draw, in the 520 years of history of the Church in Brazil, the lights to understand the origins of the social and environmental crisis, in the colonial period, in the Empire and in the Republic, reaching to the present day. In the second chapter, we present the christology and the soteriology of the encyclical letter Laudato Si’ approaching creation, incarnation and redemption in an integral and interdependent way. Finally, in the third chapter, we study the ecotheology of the Sanctuary Christ the Redeemer from its fundamental symbolism, the Cross, the Ressurrection, the Sacred Heart of Jesus, the Eucharist and Our Lady of Aparecida, in order to seek answers to our propositions. The resulting ecotheology from this research presents creation, incarnation and redemption in a legitimate and original interdependent relationship, through the symbolism of the mountain and of the statue of Christ the Redeemer, demonstrating that the entire ecosystem, and not just the human being, participates in the divine salvific project.
