One of them was Dr. Stefan Bankov, perhaps the immigrant with greatest influence for the Bulgarian Protestant scholasticism. Immigrating to the United States in 1969 after being severely persecuted in Bulgaria, Bankov earned a doctoral degree in theology and dedicated his life to one great purpose, namely the preparation of the first concordance of the Bulgarian Bible. The concordance was completed in 1986 before the era of the personal computer. After the fall of the Berlin Wall, Bankov returned to Bulgaria to work with his home church of Bourgas. He is the founder and president of East-West Christian Solidarity, a nonprofit religious organization based in California which aims to provide Christ-centered evangelism, preaching, teaching, and humanitarian for Bulgaria.
