The image used here is actually from a more recent mission, rather than the one Sagan used in his famous meditation.
“Jesus came on cold straw, Jesus was warmed by the breath of an ox. “Who is this?” the world said. “Who is this blue-cold child and this woman, plain as the winter? Is this the Word of God, this blue-cold child? Is this His will, this plain winter-woman?” The world said, “Love cuts like the cold wind and the will of God is plain as the winter.”
