Recent years have seen a plethora of research accomplished with respect to OT poetic prayers, predominantly in relation to the Psalter, with a least one ramification being a lack of engagement with the full spectrum of expressions especially within OT prosaic prayers. In addition to this, contemporary pastoral literature continues to exhibit an underdevelopment with respect to the full anthropological spectrum of expressions amidst grief especially within intercultural contexts. Observing both lacunas in scholarship, this dissertation operationalizes a Revisionist Method of Mutual Critical Correlation as its metamethod while incorporating Renewed Form Criticism, Hermeneutical Phenomenology, annd a Liberative Intercultural Praxis as it pursues a twofold objective: 1) an examination of the multivalent expressions (i.e., verbal, physical, and emotional) that leading Israelites pray-ers within the ancient context of OT prosaic prayers communicated to/before God while in the crux of disorientation, and 2) an investigation into the multivalent expressions (i.e., verbal, physical, and emotional) that leading Christian pray-ers wtihin an intercultural context (i.e., among Canadian immigrants from Guyana and Vietnam) communicated to/before God amidst the phenomenon of grief. At the heart of attending to this twofold mission is the configuration of an expressive domain of anthropological expressive modalities of disorientation communicated to/before God, along with their essence or meaning. Sensitized to such an expressive domain with its multivalent significance, contemporary pastoral caregivers would thus be better equipped to foster compassionate, liberative intercultural pastoral care for intercultural Christian communities coping with grief.
