It is generally acknowledged that Hinduism, as the name of a distinct religion, did not exist before the nineteenth century. Before that, “Hindu” had simply meant “Indian” and encompassed a variety of beliefs and practices (diffuse spirituality). There were also indigenous “Thomas Christians” dating fromthe 1st century CE. When missionaries arrived, lower caste groups found Christianity attractive. A sea-change occurred around the nineteenth century when Westerners found “Hinduism” to be incurably superstitious. Indians responded by reforming their practices (towards concentrated spirituality). Christianity continued to appeal to marginalized groups such as women, untouchables, and aboriginal ethnic groups. Hindu nationalists continue to view Christianity with suspicion.
