The Catechism, or Education Obligatory to Every Christian (Lithuanian: Katekizmas, arba mokslas kiekvienam krikščioniui privalus, original Lithuanian: Kathechismas, arba Mokslas kiekwienam krikszczionii priwalvs) of Mikalojus Daukša was the first Lithuanian-language book printed in the Grand Duchy of Lithuania. It was published by the press of Vilnius Jesuit Academy in 1595 with financial support of Bishop Merkelis Giedraitis. The catechism is not an original work but a translation. As such, the work holds little value in terms of content, but is extremely valuable to the study of the Lithuanian language due to its lexical richness. The sole surviving copy is kept at Vilnius University Library.
