Since Christ told those He visited in the Americas about the people in Jerusalem, we could speculate that He would also have told the “other sheep” outside those two geographical areas about His “sheep” both in Jerusalem and in the Americas.
The following are direct quotaitons from Parfitt’s book:
“Western missionaries active in the country [Burma, now Myanmar] had formed the view that the Karen ethnic group was itself of Jewish extraction. This view is still held by some people and, as will be shown, has a bearing on the claims to Jewishness of many thousands of people on the Burmese-Indian border, some of whom have already emigrated to Israel. (p. 123)
“The Karens’ account of their origins— that they were from River of Running Sand—no doubt served as a springboard for all sorts of speculation. This was a people with a mysterious past. Quite clearly there were striking and seductive similarities between their legends and those of the Jewish scriptures: an example was the Karen story of creation which ‘was almost parallel to the Mosaic account in Genesis’ (p. 124-5).
“Francis Mason of the American Baptist Foreign Mission Society arrived in Burma in 1814 and in time became convinced that the Karen were part of the Lost Tribes of Israel. He had certainly reached this conclusion by 1833: on 6 December of that year he announced from his headquarters in the ‘head waters of the Tenesserim’ to Mr. Maingy the British Civil Commissioner, who had requested a report on the Karen, ‘the discovery of a fragment of the descendants of the Hebrews’. ‘I sit down in the midst of the Karen jungle,’ he wrote, ‘to redeem my pledge and give you some account of the traditions existing among the Tayoy Karens.’ In a passionate letter Mason listed the traits that proved their distinguished lineage: the nature of their god Pu or Yuwah, their belief in angels and Satan, the fall of man, the dispersion of Babel, the future destruction of the world, their love of God, their tradition of being a wandering people, their freedom from idolatry and so on. ‘There can scarcely be a rational doubt that the Yuwah of the Karens is the Jehovah of the Hebrews---from the foregoing I am constrained to believe the Karens to be descendents of the Hebrews. Look at them, sir; is not the Jew written in their countenance?’ (p. 125)
“Above all, it was the cult of the high god Yuwah or Ywa, reminiscent of the Hebrew YHWH, which excited Christians and later Jews and inspired them with the certainty that here must be some long-lost relic of the ancient religion of the Hebrews--- According to Father Plaisant, the early Baptist missionaries had got it about right: Yuwah created the earth, he made man and all living creatures, he was omniscient, omnipotent, perfect and eternal. According to the priest, in the days after the creation Yuwah set aside the ‘book of gold’ for the Karen, who failed to come and get it. It was therefore entrusted to his younger ‘white brother’. ‘Therefore---the latter obligingly built a boat for Ywa and transported him across the ocean, whence Ywa ascended to heaven. In their sacred songs, the Karen look forward to the return of the White Brother and their book, as well as to the advent of Ywa.” (p. 127)
