The Concept of Incarnation in Christian Theology and in the Spirituality of Rut Björkman

This paper explores and compares the ontological structures of the incarnation as defined in traditional Christian theology versus the mystical spirituality of Rut Björkman. Traditional Christian Christology, rooted in the Council of Chalcedon (451), defines the incarnation as a unique, substantial "hypostatic union". Within this framework, the divine person of the Logos subsists in two distinct natures—divine and human—without mixture or separation, operating from a "top-down" metaphysical trajectory. In contrast, Rut Björkman approaches the incarnation from a "bottom-up" mystical perspective. Rather than a singular historical event restricted to Jesus, Björkman views the incarnation as a universal, transient process accessible to every human being. In her spirituality, the incarnation is realized whenever an individual achieves a successful mystical union. The subject of this union is an apersonal, divine "creative power," which acts immanently within the human person as a tool of grace, rather than forming a substantial or hypostatic bond. Consequently, figures like Buddha, Lao-Tzu, and Paul are similarly regarded as historical expressions of this mystical realization. By analyzing the underlying ontological assumptions of both models, the study highlights several open philosophical challenges. For Christian theology, these include the problematic nature of the substance concept, the potential for volitional conflict between Christ's two wills, and the existential-ontological interpretation of the resurrection—vividly illustrated by the theological debate regarding what a running camera would have recorded in Jesus' tomb. For Björkman’s model, the primary challenge lies in the tendency toward a universal world soul and the depersonalization of the human ego to accommodate the divine force. Ultimately, the paper concludes that while both frameworks diverge significantly in their dogmatic and existential intensity, they share a foundational hylomorphic intersection: both conceive of the incarnation as an informational, ontological reality that establishes a profound union between a formal divine principle and material human reality.
