This book is a manual of instruction in the Catholic Faith
written in the form of a dialogue by a Jesuit with the purpose of cautioning the Filipino Catholic beset by Protestant
propaganda at the beginning of the American period. The
book is divided into two parts: Part One deals on the subject of
the true Church of Jesus Christ; Part Two presents
Protestantism and its principal errors and a defense of Catholic
dogmas.
