In Charles E. Curran's latest book, Diverse Voices in Modern US Moral Theology, he presents the diverse voices of US Catholic moral theologians from the mid-twentieth century to the present. The book discusses eleven key individuals in the development and evolution of moral theology as well as the New Wine, New Wineskins movement. This diversity, which differs from the monolithic understanding of moral theology that prevailed until recently, comes from the diverse historical circumstances or Sitz im Leben of the authors. Each of these theologians developed her or his approach in light of these circumstances and in response to shifts in the three audiences of moral theology—the Church, the academy, and the broader society.

By exploring this diversity, Curran recognizes the deep divisions that exist within Catholic moral theology between the so-called "liberal" and "conservative" approaches and acknowledges the need for greater dialogue between them, providing a deeper understanding of the methods and approaches of these significant figures. 

This new book from a major figure in the field will be an important resource for students and scholars of US Catholic moral theology and for anyone seeking to understand the current state of moral theology in America today.
