She could well be …

… Therese of Lisieux, dangerous saint - Aleteia.

Therese takes away every excuse, dismissing every good reason we can give for not being holy, for not at least striving after sanctity. She’s proof that great holiness is possible for every soul, and so our lack of sanctity is a matter of our own will, rather than our luck or our circumstances. In other words, Therese’s message is this:  If we’re not holy it’s because we don’t want to be.
