“Here is an old Christmas card,” the priest said. “When I used to visit these nuns, I was amazed by the face of Sister J. Look at the group photo. Look at her face. It’s always like this. It’s like she is always living in the grace of God.”

That’s Transfiguration. Every Christian, perhaps everyone, intuitively knows that it’s possible and that they may have seen it. It’s only some sort of prejudice or intellectual difficulty that would let us think otherwise.

The intuition is there: Holiness, though only the Spirit can control the different and sometimes strange modes in which it is visibly manifested in our obscure flesh, can be seen. That’s the religion of the Incarnation.
