Dear Lucyna,

There are several Catholic Bibles in English. Here's a summary:

Douay-Rheims Bible - from the 17th century; like a Catholic equivalent of the King James Version

New American Bible - very popular in the US; done entirely by Catholic translators

Revised Standard Version, Catholic Edition - excellent translation by Protestant, Catholic, and Orthodox scholars

New Revised Standard Version, Catholic Edition - revision of the RSV; uses egalitarian language, e.g. Psalm 1 reads "Happy are those" instead of "Blessed is the man"

Jerusalem Bible - based on a French translation made by the Dominicans; I'm told it's very popular in Ireland

New Jerusalem Bible - revision of the Jerusalem Bible; uses egalitarian language

Knox Bible - scholarly translation intended to clarify passages in the Douay-Rheims Bible

Confraternity Bible - predecessor of the New American Bible

I hope this helps. Here are links to online Bibles:
