The Dual Language Theory View of Human Nature: A Unified Psychological–Biblical Anthropology

Abstract

The Dual-Language Theory (DLT) offers a meta-integrative framework for understanding human nature that synthesizes contemporary psychological science with Christian theological anthropology. DLT posits two complementary interpretive languages: the Language of Function (psychological descriptions of neurobiological mechanisms, relational processes, and behavioral patterns) and the Language of Formation (biblical revelation of identity, moral ontology, spiritual purpose, and eschatological telos). Through eight core dimensions—integration, storiedness, relationality, woundedness, transformability, dignity/agency, meaning-orientation, and synthesis—this article articulates a multi-level anthropology that addresses longstanding tensions between empirical psychology and theological sufficiency. Drawing on trauma theory (van der Kolk, 2014), attachment research (Siegel, 2012), narrative psychology (McAdams, 2013), interpersonal neurobiology (Schore, 2012), and Christian psychology (Johnson, 2017), DLT provides conceptual coherence for clinicians and pastors navigating complex trauma presentations within faith-based contexts. Clinical implications, training applications, and empirical research recommendations are proposed to operationalize DLT as a testable model of whole-person transformation.
