"This revised edition takes you on a tour of Divine Mercy throughout salvation history, through the Old and New Testaments, in the writings of the Church's great theologians, and in the lives and writings of the saints down through the ages. In this revised edition, Dr. Stackpole expands his chapter on the great theologian St. Augustine, includes a new chapter on the spiritual master St. Bernard of Clairvaux, and highlights the involvement of Pope Benedict XVI at the first World Apostolic Congress on Mercy in 2008"--Publisher's description.
