Being rooted in imagery and metaphor, Jungian psychology suggests that metaphors are expressions of archetypal imagery. While extensive research has examined how archetypal theory informs literal metaphors across various languages, less attention has been paid to whether metaphorical conceptualizations can serve as a modality—similar to dreams or active imagination—for representing archetypes and the collective unconscious. Linguistic data from intercultural interactions are crucial for uncovering shared conceptual structures across diverse communities. This study explored the "Document on Human Fraternity for World Peace and Living Together" signed by Pope Francis and the Grand Imam of Al-Azhar as a pivotal text in contemporary interfaith dialogue. We analyzed how the processes of metaphorizing archetypes were woven into this discourse. Specifically, we investigated whether archetypes are represented within the conceptual blending processes of metaphors, how the collective unconscious is reflected in the conceptual metaphors employed in interreligious dialogue, and how these metaphors may foster shared understanding among religious leaders. Using Conceptual Blending Theory (CBT), we identified metaphorical expressions that projected archetypal content, revealing the presence of key Jungian archetypes, such as the Mother, Rebirth, Shadow, Innocent, and God-Image. Our findings indicated that significant shared conceptualizations existed between Islamic and Christian leaders, which were grounded in the collective unconscious and articulated through archetype-based conceptual metaphors.
