Gods with Passports: How Buddhism, Christianity, and Islam Changed as They Crossed Borders

Readers travel from Gandhara, where the Buddha appeared on Kushan coins with his name spelled in Greek letters, to the translation workshops of Luoyang and Chang’an, the monasteries of Tibet, and the court of Yamato, where a gilded statue divided Japan’s nobles. They meet Syriac monks in Persia and Kerala, a monk from Beijing received by the king of France and the pope, Nubian bishops painted on cathedral walls, Saxon poets who turned Christ into a warrior lord, and an Icelandic lawspeaker who settled his country’s faith after a night under his cloak. They watch Persian become a language of Islam, a West African king convert after a prayer for rain, Mongol khans embrace Islam without abandoning the law of Genghis Khan, Javanese saints preach with shadow puppets, and Chinese scholars explain the Qur’an in the words of Confucius.

This is not a contest over which faith spread fastest or proved most tolerant. It is a history of mechanisms: what gets translated, what is kept, what is blended, and what provokes resistance. Kings, merchants, pilgrims, and translators all left their mark, and every border reshaped belief and practice. Vivid, grounded in the sources, and truly global in scope, Gods with Passports shows how a faith can remain recognizable while becoming something new wherever it goes.
