Rev. Peter Deyneka, an immigrant from the former Soviet republic of Belarus, founded Slavic Gospel Association (SGA) in 1934. Rev. Deyneka had a fervent desire to reach his own people with the Gospel of Jesus Christ. Over the decades, SGA wrote and edited many Russian-language materials, which helped strengthen and encourage the oppressed, faithful Christians living behind the Iron Curtain. SGA still maintains this library of materials and is now adapting them to modern technology.
