Following Mother Teresa's death in 1997, the Holy See began the process of beatification, the second step towards possible canonization. This process requires the documentation of a miracle performed from the intercession of Mother Teresa. In 2002, the Vatican recognized as a miracle the healing of a tumor in the abdomen of an Indian woman, Monica Besra, following the application of a locket containing Mother Teresa's picture. Monica Besra said that a beam of light emanated from the picture, curing the cancerous tumor. Some of Besra's medical staff and, initially, her husband insist that conventional medical treatment eradicated the tumor.[62] Unless dispensed by the Pope, a second miracle is required for her to proceed to canonization.
Christopher Hitchens, a British-born American author, journalist and literary critic, was the only witness called by the Vatican to give evidence against Mother Teresa's beatification and canonization process, as the Vatican had abolished the traditional "devil's advocate" role that filled a similar purpose.[63] Hitchens has written that Mother Teresa's own words on poverty proved that "her intention was not to help people", and he alleged that she lied to donors about the use of their contributions. “It was by talking to her that I discovered, and she assured me, that she wasn't working to alleviate poverty,” says Hitchens. “She was working to expand the number of Catholics. She said, ‘I'm not a social worker. I don't do it for this reason. I do it for Christ. I do it for the church.’"[64] In the process of examining Teresa's suitability for beatification and canonization, the Roman Curia (the Vatican) pored over a great deal of documentation of published and unpublished criticisms against her life and work. Vatican officials say Hitchens' allegations have been investigated by the agency charged with such matters, the Congregation for the Causes of Saints, and they found no obstacle to Mother Teresa's canonization.[citation needed] Due to the attacks she has received, some Catholic writers have called her a sign of contradiction.[65]
