Nestorian Christianity over 1000 yrs ago brought the Sabbath to the Islands in the Indonesia areas - specifically Borneo - and the Dusun  People.   After 1000+ yrs SDA missionaries discovered them still keeping Sabbath in the isolated mountains of Borneo. A friend of mine told me his personal experiences among them and sent pictures, but that has been yrs ago. He no longer works with them the most local SDA Conference is doing that and he is elsewhere.  Don't know where to find those pictures.

The Nestorian Sabbath keeping Christians traveled far, maybe only the records of Heaven can show everywhere they went and spread Sabbath & Jesus as the Lord of the Sabbath all along their wide travels.   It is possible that evangelism impelled them and persecution drove them and they shined every where they found listeners and hearts in need.
