Both papers included in this book were presented at the Society for Pentecostal Studies. The first paper, although heavily edited to fit the format, was published in vol. 30 (2010) of Assemblies of God Heritage magazine under a new title, "Ivan Voronaev: Slavic Pentecostal Pioneer and Martyr." Some of the historical data we presented in the article was published openly for the first time. Our research was further mentioned in the December, 2010 AG Heritage editorial. The Bulgarian "Evangel" also published our translations of Voronaev's correspondence. In 2011, Vladimir Franchuk, translated parts of the Voronaev's papers in Russian and included it in his book "Revival: from the center of Odessa to the ends of Russia," thus making our research available to the Slavic people just in time for the 90th Anniversary from the beginning of Ivan Voronaev's Pentecostal ministry in Russia. Unfortunately, with all this interest, little attention was given to the second paper concerning the Voronaev children until now.
