Apparently, it's a growing field:
Some scholars take the search for Gospel themes in the Harry Potter series quite far. Oona Eisenstadt, an assistant professor of religious studies at Pomona College, offers a particularly elaborate analysis, arguing that Rowling explores the complex natures of biblical characters by presenting two versions of each in the Potter books. Snape and Malfoy, she argues, represent competing understandings of Judas - each seeking to kill Dumbledore, but one because he is serving evil and one because destiny demands it. Eisenstadt sees Dumbledore and Harry, in different ways, as Christ figures - perhaps Harry representing the human Jesus, and Dumbledore the divine. And she posits that the New Testament depiction of elements of the Jewish community is represented by the goblins (unappealing bankers) and the Ministry of Magic (legalistic and small-minded).
