"All Can Be Saved" explores the diverse and often overlooked religious views in colonial Latin America, particularly among the common people who challenged the rigid doctrines imposed by the Spanish and Portuguese empires. The book delves into the personal beliefs and practices of individuals who, despite the threat of the Inquisition, dared to express and follow their own interpretations of Christianity. Through extensive archival research, the author reveals a complex tapestry of faith that includes dissenting views on salvation, morality, and the authority of the Church, highlighting the spiritual autonomy and resistance among the colonized populations in the face of imperial and religious domination.
