Abstract
The article critically examines Hans Urs von Balthasar’s core intuition that human holiness has apologetic value for Christianity. It argues that von Balthasar’s claim relies on two notions of ‘proof’, and, in distinguishing between the two notions, it clarifies his position. This clarification is followed by a defense of von Balthasar’s view that it can be rational to accept Christian faith on the grounds of human holiness. However, by way of conclusion, the article proposes that von Balthasar’s intuition could, in principle, be applied to a variety of both religious and non-religious traditions, which thus undermines his assumption that human holiness has apologetic value for Christianity alone
