Was Shakespeare a Closet Catholic?

From the Telegraph:

The Vatican's official newspaper has claimed there are "few doubts" that William Shakespeare was a Catholic.

L'Osservatore Romano, a week after proclaiming Tintin a Catholic hero, said the Bard's plays "teem with open references to the Catholic religion."

The newspaper reopened a debate which has raged ever since an Anglican archdeacon said of Shakespeare a few decades after his death: "He died a Papist."

In a lengthy article which appeared alongside a review of the new Shakespeare film, 'Anonymous', L'Osservatore Romano (The Roman Observer) said the references to purgatory in Hamlet and other plays betrayed distinctly Catholic beliefs and marked Shakespeare out as a crypto-Catholic.
