The citizens of the planet Lithia are some of the most ethical sentient beings Father Ramon Ruiz-Sanchez has ever encountered. True, they have no literature, no fine arts, and don't understand the concept of recreation, but neither do they understand the concepts of greed, envy, lust, or any of the sins and vices that plague humankind. Their world seems darned near perfect. And that is just what disturbs the good Father. First published in 1959, James Blish's Hugo Award-winning A Case of Conscience is science fiction at its very best: a fast-paced, intelligent story that offers plenty of action while at the same time explores complex questions of values and ethics. In this case, Blish has taken on the age-old battle of good vs. evil. Lithia poses a theological question that lies at the heart of this book: is God necessary for a moral society? The Lithians are nothing if not moral. Not only do they lack the seven deadly sins, they also lack original sin. And without any sort of religious framework, they have created the Christian ideal world, one that humans would be eager to study and emulate. But is it too perfect? Is it in fact, as Father Ruiz-Sanchez suspects, the work of The Adversary? And what role does Egtverchi, the young Lithian raised on Earth, play? Is he an innocent victim of circumstance, or will he bring about the Dies Irae, the day of the wrath of God, upon the earth?

That said, Arthur C. Clarke's The Star -- http://www.uni.edu/morgans/astro/course/TheStar.pdf -- is weaker on the technology but stronger on the heartstring-tugging. It is also a great story, in a similar vein.
And relevant to The Star, but not really in the same vein, there's James Blish's novel A Case of Conscience ... http://en.wikipedia.org/wiki/A_Case_of_Conscience
