This book is a thorough (450-page) but clear explanation of the Doctrine and beliefs of the Catholic Church. I would recommend this book to anyone looking to understand Catholic ideas more firmly, especially anyone teaching the faith to others - parents, school teachers, those in ministry.
Fr. Peter also dialogues with the beliefs of the current world, addressing key moral dilemmas and misunderstandings of the Church in the world today, including the advances of science, the roles of both justice and charity in economics, and the prevalence of loneliness and despair.
I especially appreciated his emphasis on the importance of a deep personal relationship with Christ, importantly through the sacraments, and the call to share the love of Christ with everyone in our lives. He shares the possibility of this goal through the concrete examples of the lives of the Saints, especially those in recent history.
