Amado T. Tumbali, Jr., S.J.’s “History of Christianity in Mindanao: Arrival, Challenges, and Development of the Catholic Church in Mindanao During the Spanish Period (1538-1897)” takes us back in time to early attempts to Christianize the island made by Jesuit and Recollect mission- aries. In this brief and fast-paced narrative, he gives us a glimpse of the different challenges faced by the missionaries as well as the various ways by which they tried to respond, including not so “religious” strategies such as building forts and diplomacy. Indeed, a timely revisit at the history of Christianity in the Philippines would be sorely incomplete if it were to focus only on landmark events and forget the unsung efforts of the countless ministers of the Gospel who labored tirelessly and creatively on the ground – some even giving up their life – to sow the Faith in these islands. – from the Associate Editor’s Preface
