Interpretation
Asia & Oceania Interpretation
While the staggering 60 million unregistered Protestants in China prove faith can flourish under any regime, the real story across Asia is that Christianity isn't merely surviving but dynamically splintering, from Seoul's megachurches to India's Baptist affiliates, all while maintaining its ancient strongholds from the Philippines to Papua New Guinea.

The numbers tell a story of a great American religious reshuffling, where the pews are emptying from the mainline but still humming in the nondenominational warehouses, proving that faith, like water, is seeking new vessels even as the overall reservoir slowly drains.
