The Revised Standard Version was a joint translation project between American Protestants and Catholics with the Catholic Church completing the translation of the Apocrypha. This translation is considered the most accurate modern translation but still contains “Thee” and “Thou” when referring to God. This translation along with the New American Bible and the Jerusalem Bible was approved for liturgical use in the United States until recently.
The Revised Standard translation was used for all quotes in the Catechism of the Catholic Church and is also the English text used in the critically praised Ignatius Catholic Study Bible.
The Revised Standard 2nd Edition updated the language by removing “Thee” and “Thou.”
