As quoted in "Rita Remains Striking, Trim, Busy" in The Palm Beach Post (16 October 1969)]
Context: Everybody else does nude scenes, but I don't. I never made nude movies. I didn't have to do that. I danced. … I was provocative, I guess in some things. But I was not completely exposed.

"Brother Zachariah said pretty much the same thing. Maybe with less sarcasm."

A Man From Lebanon: Nineteen Centuries Afterward
Jesus, The Son of Man (1928)
Context: Here and there, betwixt the cradle and the coffin, I meet your silent brothers,
The free men, unshackled,
Sons of your mother earth and space.
They are like the birds of the sky,
And like the lilies of the field.
They live your life and think your thoughts,
And they echo your song.
But they are empty-handed,
And they are not crucified with the great crucifixion,
And therein is their pain.
The world crucifies them every day,
But only in little ways.
The sky is not shaken,
And the earth travails not with her dead.

The Pessimist, reported in Bartlett's Familiar Quotations, 10th ed. (1919).
