America's Share in the Regeneration of Bulgaria. (1840-1859.) [1] Page 37 "Neofit was a Macedonian and his translation of the New Testament was made in his native dialect. Considering his proneness to use Slavic forms in his previous works, which he published in 1835, it is fair to suppose that his manuscript of the Bible was not less free from them; but these have all disappeared in the printed book, no doubt at Riggs' suggestion or through his correction. He insisted on a pure Bulgarian of the Western (Macedonian) type, since for a time to come he expected to confine his missionary efforts to the country this side of the Balkan mountains. The Gospels were frequently reprinted and were received by the people with the greatest enthusiasm, and for a period of two decades served as a model for the written idiom of the nation. Later, when culture penetrated into Bulgaria Proper, this abnormal state of raising a dialect spoken beyond the provinces of the country to the dignity of a literary language could not be maintained. When the Eastern dialect began to rise in importance, Riggs was among the first to adopt it for his translation of the whole Bible, but previous to the sixties, Neophytos' New Testament and Riggs' religious and ethical tracts formed the basis for all other literary productions."
