The Vision of Peace collects two dozen of Maguire's essays and letters, many of which describe the connections between her political action and her faith. Although most of the writing concerns Northern Ireland, essays about the Holocaust, India, East Timor, and Yugoslavia are also included. Throughout, Maguire urges readers to develop a "politics of mercy and forgiveness," and communicates her belief that
hope for the future depends on each of us taking non-violence into our hearts and minds and developing new and imaginative structures which are non-violent and life-giving for all.... Some people will argue that this is too idealistic. I believe it is very realistic.... We can rejoice and celebrate today because we are living in a miraculous time. Everything is changing and everything is possible.--Michael Joseph Gross
