China - A.D.781
In A.D. 781 the famous China Monument was inscribed in marble to tell of the growth of Christianity in China at that time. The inscription, consisting of 763 words, was unearthed in 1625 near the city of Changan and now stands in the "Forest of Tablets," Changan. The following extract from the stone shows that the Sabbath was observed:
"On the seventh day we offer sacrifices, after having purified our hearts, and received absolution for our sins. This religion, so perfect and so excellent, is difficult to name, but it enlightens darkness by its brilliant precepts." Christianity in China, M. I'Abbe Huc, Vol. I, ch.2, pp. 48, 49
