St. Francis Xavier, a founding member of the Jesuits, played a pivotal role in the Counter-Reformation by expanding Roman Catholicism into Asia through innovative missionary strategies.123

Rather than merely passing through regions, Xavier emphasized long-term commitment. He advocated for adapting to local customs and languages, using friendship and sincerity to bridge cultural divides. To ensure the faith endured, he prioritized the education of native clergy and the establishment of schools, seminaries, and charities, rather than leaving converts with only the rite of baptism.143

His efforts included:
* India: He worked among the Paravas and Macuans, using translated catechisms to instruct thousands. He also developed the College of Holy Faith in Goa to train local priests.3
* Malay Archipelago: He founded missions among the Malays and indigenous groups in the Moluccas.3
* Japan: He sought to establish a deeply rooted church led by educated native clergy, a revolutionary approach at the time.4

While his work was foundational, it was also complex; he notably advocated for civil protections for converts but was also involved in the Goa Inquisition, which punished those who practiced other religions.4
