Answer:
While in Guam, Calungsod preached Christianity to the Chamorro people through catechesis, while baptizing infants, children, and adults at the risk and expense of being persecuted and eventually murdered. Through Calungsod and San Vitores's missionary efforts, many native Chamorros converted to Roman Catholicism.
Calungsod was beatified on March 5, 2000, by Pope John Paul II, and canonized by Pope Benedict XVI at Saint Peter's Basilica in Vatican City on October 21, 2012.[5]
