I've been thinking about Philip Jenkin's book, The Lost History of Christianity, and how it describes the spread of Christianity "eastward" all the way to India and China. The Nestorian Stele is one such artifact of a history that is mostly forgotten.
Although it’s a world religion, in a sense it is multiply cut off from its roots. While its key early figures used one language, its scriptures are translations of those early words. And although it was once very strong in the land of its birth, it subsequently became much more numerous in lands far afield, while it virtually died in that first homeland. Later believers might be surprised how much was transformed as the original faith moved from its oldest home. https://www.patheos.com/blogs/anxiousbe ... n-decline/
