¡Caiñgat Cayo!
 Sa mañga masasamang libro,t, casulatan

by Fr. José Rodriguez

"¡Caiñgat Cayo!" by Fr. José Rodriguez is a religious pamphlet written in the late 19th century. This work serves as a condemnation of certain books considered harmful to the Catholic faith, particularly targeting the writings of Filipino nationalist José Rizal. The pamphlet reflects the tensions between colonial powers and emerging nationalist sentiments during a time of significant political and social upheaval in the Philippines. In the pamphlet, Fr. Rodriguez emphasizes the dangers of reading literature that he categorizes as "bad" or "heretical," warning readers that engaging with such texts could lead to severe spiritual consequences, including excommunication. He lists various types of works deemed harmful, including those that challenge religious beliefs, promote immorality, or lack proper ecclesiastical approval. Furthermore, he urges the faithful to avoid these writings and to actively destroy them if encountered, framing this issue as a matter of moral and spiritual duty. Throughout the text, Rodriguez’s strong tone reflects the Catholic Church's efforts to maintain its influence over the minds and actions of the Filipino people during a pivotal era.
