On Sex

The modern man isolated from faith, from raising his desire for God into a conscious desire, is sunk into the position of seeing physical love as an end it itself...The Sex act is a religious act & when it occurs without God it is a mock act or at best an empty act.

From The Habit of Being...

There is a moment of grace in most of the stories, or a moment where it
is offered, and usually rejected. Like when the Grandmother recognizes
the Misfit as one of her children (a child of God) and reaches out to
touch him. It’s the moment of grace for her anyway—a silly old woman—but
it leads him to shoot her. This moment of grace excites the devil to
frenzy.

Pornography

Pornography...is essentially sentimental, for it leaves out the connection of sex with its hard purpose, and so far disconnects it from its meaning in life as to make it an experience for its own sake.
