The Lutheran Church was named after its founder Martin Luther, though he himself preferred that they should just be called Christians. In the 16th century, Luther challenged some of the teachings and practices of the church of his time, calling the church back to its roots in Scripture. The change that followed became known as the Reformation of the Church in Europe. He also translated the Bible from Latin into German, the language of the common people in his country. The printing press and the work of translators have now made the Bible readily available in almost every language.
