“Christianity,” however, as a revealed worldview, has an objective definition. Christianity centers ultimate reality and, therefore, ultimate authority, outside (not within) the created order, locates it in a Divine Personal Being who has made Himself known through what He has made, through Holy Scripture, and ultimately made known Himself through Christ Jesus. One might doubt that there is a God who has revealed Himself or that God has revealed Himself in these ways, and therefore reject Christianity. But because Christianity is a worldview that comes already carefully defined, it’s not open to mass-scale revisions.
