With Unconfined Wings — Sarah A. Hoyt

Space is vast and the human soul is small. In this infinity the nuns of the order of St. Lucia of The Spaceways stand, athwart the cold and the nothingness. They nurse the sick, they care for the dying, they raise the young. And if their work requires them to serve drinks and pack guns, they do that too, sure that He helps those who help themselves.

A short story.
