Within 50 years of missionary life, Angel crosses cultures to understand better Paolo Freire's methodology through real-life applications, traversing Europe to Asia and Latin America, from Vatican to Quezon City, wholeheartedly spreading the Claretian Spirit among humanity, whilst experiencing the people's poverty and hardships. Author Maria Frencie Carreon pens how Claretian missionary Angel Calvo breathed through harsh spaces in a period of Martial Law, in times of fear and trauma of domestic terrorists abducting religious leaders, in years if heart-gripping homelessness of the urban poor, in agonizing months of trafficked young women and children, and in sleepless nights for wandering street children. In such soul-clinching experiences, when one finds breathing moments of life - whether his or others'. he finds the essence of God's mission for him.
