This article seeks to investigate Martin Heidegger’s ontological philosophy in connection with the symbols of suffering present in the Passionist Congregation and their significance for Christian faith. The article follows a structured literature review approach, examining a range of sources such as Karl Rahner’s Foundations of Christian Faith: An Introduction to the Idea of Christianity, Louis-Marie Chauvet’s Symbol and Sacrament, as well as other works discussing Heidegger’s ontological philosophy like Armada Riyanto’s Relasionalitas and F. Budi Hardiman’s Heidegger and the Mysticism of Everyday Life: An Introduction to Sein und Zeit. Through this analysis, it is revealed that the symbols of suffering within the Passionist Congregation function as a "living body" that allows individuals to engage in contemplation and participation in the suffering of Jesus, ultimately facilitating the internalization of the Gospel’s teachings. Additionally, these symbols play a crucial role in enabling Christians to cultivate a close relationship with God through the suffering experienced by Christ.
