Henri Daniel-Rops covers the lives of Eleven saints who, as the cover of his 1959 version of this book indicates "were truly The Heroes of God who carried the cross to the far corners of the earth. St. Paul, of course, was the first. The others were among the many heroes who followed in his steps; St. Martin, who began as a Roman soldier; Blessed Ramon Lull, who wanted to be a troubadour; Bartolome de las Casas, son of the Conquistadors; St. Francis Xavier, Jesuit soldier of Christ; St. Isaac Joques, scalped by the Indians he loved; Fra Junipero Serra, the creator of California; Mother Javouhey, the nun who may truly be called "a great man"; Charles de Foucauld, the white hermit of the Sahara [and who has since the writing of this book been proclaimed a saint]; Father Damien, who embraced the living death of leprosy [and who also has been proclaimed a saint since the writing of this book] and Father Nussbaum, martyred in forbidden Tibet. These ten men and one women were adventurers of God, spokesmen of Christ, typical of the many missioners who, over two thousand years, have given their lives and deaths to be The Heroes of God."
