This is the fifth essay is a series focusing on the distinctives of Catholicism. I have attempted to demonstrate in the previous essays that two broadly Christian theologies, the Incarnation and the Messianic Prerogative, are distinctly Catholic in origin and nature. I have also begun outlining the parallelisms between the Christian doctrine of exclusivity and the details of the Catholic theology of exclusivity. In my third essay, I outlined Catholicism’s unique claim to salvific exclusivity.
