What version of the Bible do the Polish Orthodox use? The Tysiąclatka or Wujka or some other version?
These two and Biblia Warszawska (Brytyjka) are the most popular.
For those who don't know: Biblia Tysiąclecia
") is a 20th century RC translation, Biblia Jakuba Wujka
") is a late 16th century RC translation, and Biblia Warszawska
") is a 20th century Protestant translation.
There is no officially approved translation.
Actually there is one: Biblia Ekumeniczna
(the Ecumenical Bible) which was translated together by Orthodox, Roman Catholics, Old Catholics and Protestants. However, it isn't used widely in our Church. As far as I know, work on the official Orthodox translation is in progress.
