Arguments against canonization can be submitted as well. 鈥淭his is where we get the phrase 鈥榙evil鈥檚 advocate,鈥欌 Robbins says. In Mother Teresa鈥檚 case, the late writer and adamant atheist Christopher Hitchens, a longtime critic of the nun, was called by the Vatican to provide evidence against her canonization. He claimed that 鈥渉er intention was not to help people, but instead expand the number of Catholics.鈥 Officials responded to Hitchens鈥 criticism by saying they 鈥渋nvestigated and found no obstacle for Mother Teresa鈥檚 beatification, thereby bestowing on her the title 鈥楤lessed.鈥欌
An essential element in the next stage of the canonization process is a requirement that at least two miracles corroborate the candidate鈥檚 sanctity. In Mother Teresa鈥檚 case, the miracles approved by the Vatican included the healing of an Indian woman whose abdominal tumor disappeared after a Miraculous Medal that had been touched to Mother Teresa鈥檚 body was placed on the woman鈥檚 stomach. The other miracle involved a Brazilian man whose wife prayed to Mother Teresa when he was suffering from a bacterial infection. He made a full recovery and went on to have two children, which doctors had said would be impossible.

Mother Teresa鈥檚 canonization takes place during the Year of Mercy, a time for the Catholic Church across the world to focus on forgiveness and healing. Following canonization, she will be known as Saint Mother Teresa, the woman celebrated for this summation of her life鈥檚 work: 鈥淏y blood, I am Albanian. By citizenship, an Indian. By faith, I am a Catholic nun. As to my calling, I belong to the world. As to my heart, I belong entirely to the Heart of Jesus.鈥
鈥淪he鈥檚 very much a saint for the modern world,鈥 Robbins says. He and other scholars expect that the canonized Mother Teresa will live large in the world鈥檚 imagination and in cultural discourse, not just because of her faith, but also because of her struggle to believe. Given that, she鈥檒l be more than a plaster-of-paris saint, Robbins says, noting that her diaries reveal a decades-long, existentialist crisis of faith, an experience of what she described as God鈥檚 absence, God鈥檚 silence.
