Despite positive reviews and three Tony Award nominations (including a nomination for the prestigious Best Play), the production was closed on – almost a month and a half before its run was due to end – prompting Fintan O'Toole to comment: "I spent three years as a critic on Broadway, and I still can't claim to understand it. In January 2013, it was announced that Fiona Shaw would star in a Broadway stage adaptation of the play, titled The Testament of Mary, produced by Scott Rudin. The first version of the text was produced in 2011 by the Dublin Theatre Festival and Landmark Productions, as a one-woman play starring Marie Mullen, Testament.
It was on the shortlist for the 2013 Man Booker Prize. However, the book was slammed and rebuked by conservative Christian circles for its blasphemous content. Initial critical reception for the book has been positive, with a reviewer for the Irish Independent writing that "To say that this is a departure for the Wexford novelist is an understatement, but it can hardly fail to be a major talking point when it's published in October." The Huffington Post also commented favourably on Tóibín's attempts to humanise Mary, saying: " The Testament of Mary is a reminder that Jesus indeed had a mother, and she was nobody's fool." No longer able to go to temple, Mary speaks to a replica of the statue of the goddess Artemis, confessing her hope that someday she will be dead. When they tell her that her son died to save the world they are angered when she tells them it wasn't worth it. Jesus's followers attempt to convince Mary that her son was the son of God and to claim that she was there to see his resurrection which she disputes. The trio eventually find safety and Mary, Lazarus's sister, departs to go home and live a normal life. She also notices that she and Mary begin having the same dream in which a flood of water returns her now resurrected son to her. The three flee through the countryside and do desperate things in order to survive with Mary eventually losing all respect for her guide as she realizes he has no plan to save them. Knowing they believe she will never abandon her son before he dies, Mary and the others flee anyway, thinking only of saving her life. As she witnesses the violent crucifixion she spies Marcus and realizes he has lured her there to be arrested like the rest of her son's followers. Mary travels to the city with Mary, one of Lazarus' sisters, and one of her son's followers, who promises protection, in order to witness the event, still believing there is something she can do to save him. Marcus visits Mary again to tell her that her son has been arrested and will be crucified. She later leaves in order to protect herself. Some of the revellers later claim that Jesus turned water into wine but Mary questions their sobriety and did not personally witness this account. At the wedding Mary tries to convince Jesus to return to Nazareth but he ignores her. In order to speak to Jesus, Mary travels to a nearby wedding where news that Jesus has resurrected Lazarus, a childhood friend, precedes his arrival. Marcus, a cousin of hers, later visited her to reveal that her son was being closely watched by Roman and Jewish authorities after appearing to cure a man who could no longer walk the cousin urged Mary to have Jesus return to live with her to save his life and not draw further ire. Mary reflects that, like many young men, her son left their small town for opportunities in Jerusalem. However they are antagonistic towards Mary because they believe her son, Jesus, was a Messiah, a claim which she refuses to support. At an unspecified age, when Mary is close to death, she is regularly visited by followers of her son who wish to record her testament before she dies.
