An Orthodox Christian from birth, Queen Olga became aware, during visits to wounded servicemen in the Greco-Turkish War (1897), that many were unable to read the Bible. The version used by the Church of Greece included the Septuagint version of the Old Testament and the original Greek-language version of the New Testament. Both were written in ancient Koine Greek, but her contemporaries used either Katharevousa or the so-called Demotic version of Modern Greek. Katharevousa was a formal language that contained archaized forms of modern words, was purged of "non-Greek" vocabulary from other European languages and Turkish, and had a (simplified) archaic grammar. Modern or Demotic Greek was the version commonly spoken. Olga decided to have the Bible translated into a version that could be understood by most contemporary Greeks rather than only those educated in Koine Greek. Opponents of the translation, however, considered it "tantamount to a renunciation of Greece's 'sacred heritage'".
