Deep in the Mekong Delta—most notably around Tây Ninh Province—Caodaism lights up the landscape with its pastel-painted temples and daily rituals. A handful of grand “Cao Đài Holy See” ceremonies still draw locals clad in crisp white uniforms, their feet echoing like clockwork on the temple’s marble floors. Beyond southern Vietnam, small communities in the U.S., Australia and France keep the faith’s eclectic spirit alive, stitching a global patchwork of followers.

Estimates today put the number of Caodaists at around 4–6 million worldwide. Vietnamese census figures hover near four million, while temple authorities and diaspora groups tip the scales toward six. Recent pilgramage tours in early 2025, promoted on social platforms like TikTok and Instagram, have sparked fresh interest—proof that an almost-century-old religion can still break new ground in a digital age.

At its core, Caodaism fuses Confucian ethics, Taoist cosmology, Buddhist compassion and Christian iconography, all underpinned by spiritist communication. That heady mix—a religious melting pot—has appealed to generations seeking a bridge between East and West. Even as Vietnam modernizes at lightning speed, Caodaism remains a living testament to cultural bricolage, quietly thriving in its spiritual backyard and beyond.
