Forms

Ἰουδαϊσμός (Ioudaïsmós) m (genitive Ἰουδαϊσμοῦ); second declension[1]

Etymology

It is formed from Ancient Greek Ἰουδαῖος (Ioudaîos, “Jew, Judaean”) + -ισμός (-ismós).[1] Bailly, Abbott-Smith and Strong derive it from the verb ἰουδαΐζω (ioudaḯzō, “to live as a Jew”), itself formed from the same noun.[2][3][4][1] Ἰουδαῖος (Ioudaîos) is from Ancient Greek Ἰουδά (Ioudá, “Judah”), from Biblical Hebrew יְהוּדָה (Yəhūḏā, “Judah”).[1]

Earliest recorded meaning

It is first found in the Second Book of Maccabees, meaning the Jewish way of belief and life.[5][3][6]

Semantic evolution

In the books of Maccabees (2 Maccabees 2:21, 8:1, 14:38; 4 Maccabees 4:26) and in a synagogue inscription from Stobi, the word names the Judaean religion and way of life.[5][3] Paul uses it in Galatians of his own former life in Judaism.[5][7][8] In the letters of Ignatius it is set against Χριστιανισμός (Khrīstiānismós, “Christianity”).[5]

Latin Iūdaismus came from it, and through Old French it gave English Judaism about 1400.[9] Modern Greek ιουδαϊσμός (iudaismós) is a learned word for the Jewish religion and for the Jews as a whole.[10]

Timeline

  • 2nd century BC – The Second Book of Maccabees uses it for the Jewish religion and way of life.[6][5]
  • 1st century AD – Paul's Letter to the Galatians uses it of his former life in Judaism.[6][5][7]
  • 1st–2nd century AD – Ignatius of Antioch sets it against Christianity.[5][11]
  • About 1400 – English borrows Judaism from Old French and Late Latin.[9]
  • Modern Greek – ιουδαϊσμός (iudaismós) is a learned word for the Jewish religion.[10]
