Final answer:
The Spanish missionaries' positive influence in the Philippines included spreading education and healthcare, while on the negative side, abuses by Spanish friars contributed to the Philippine Revolution and the fight for independence.
Step-by-step explanation:
In the Philippines' history, religion has played both constructive and destructive roles. A positive event influenced by religion was the influence of Spanish missionaries Christianizing the Philippines, which led to the spread of education and the introduction of Western culture. Churches were established, and these were sometimes the first places where Filipinos could learn to read and write, and where healthcare services were provided. On the negative side, the Philippine Revolution against Spanish rule at the end of the 19th century was in part fueled by religious abuse. Spanish friars owned vast estates and exercised significant power, often oppressing the local population, and abuses by the religious establishment helped to ignite the fight for independence.
