What is the author's style in Doubt by John Patrick Shanley?

Although Shanley clearly takes as his subject the sexual abuse scandal that has plagued the Catholic Church for years, he has said that he did not set out to write a play about that situation. The true subject of Doubtis, as its title indicates, uncertainty. The play's subtitle is “A Parable,” indicating that it is not meant to be any sort of analysis of the events described in the newspapers. Although the play takes place at a Catholic school, it does not explicitly address intricate matters of Catholicism; instead, it uses its setting to examine a human predicament that can occur in any religion or profession.
