Using Luther’s biblical interpretations, the Spiritual Exercises of St. Ignatius of Loyola, and Peirce’s Abduction, this thesis reveals that justification involves two interrelated human processes coupled with self-actualization. It illuminates the Chalcedonian formula while demonstrating the disruptive effect of Trinitarian love and Christ’s salvific gift. This thesis promotes a path towards Christian unity and the fostering of interdisciplinary and interreligious dialogues.
