[Martin] Luther asserted that our righteousness before God (coram Deo) is received and defined by faith. Our righteousness before one another (coram mundo), on the other hand, is active and defined by service. The passive righteousness of faith (vertical righteousness) is what makes us right before God – fully and finally. The active righteousness of work (horizontal righteousness) serves the well-being of creation and culture by loving and serving our neighbors.
