Er, maybe loosely, but the previous definition by Makk was correct. Though, he failed to point out that the more contemporary usage of the phrase refers not just to Jesus, but messiah-like figures, often sarcastically.
Prodigy itself has multiple meanings, by the way. The most common has been cited; one who takes easily and naturally to a difficult task, skill, orientation, or thought process.
Other meanings are a play on the original, however, and are somewhat invalidated by this. I believe the roots of the "prodigal son" stem from "prodigy", but it has been changed.
Sorry to be so pedantic, I'll go *poof* now.
