A Christian's Pocket Guideto Mary offers a biblical account of Mary's character, contrasting this with the Roman Catholic traditions which have developed throughout history, distorting her nature from an obedient servant and worshiper of God to a worshiped saint herself. De Chirico writes with the authority of thorough research as well as personal experience of the traditions surrounding Mary which have become so integral to Roman Catholic worship.

Who are the Popes and how does the Roman Catholic Church define their role? What about the present day Popes? What is the ecumenical significance of the Papacy and what are its prospects in the global world?
