The Revised Standard Version Catholic Edition (RSV-CE, also known as The Ignatius Bible) is an English language Bible translation, a Catholic adaptation of the Revised Standard Version (RSV) which updated the King James Version (KJV) into modern English. Noted for the formal equivalence of its translation, it is widely used and quoted by Catholic scholars and theologians and, because of its significance in the development of the English Bible tradition, the Revised Standard Version Second Catholic (RSV-2CE or Ignatius) Edition is "the sole lectionary authorized for use" in the liturgies of the Personal Ordinariates for formerly Anglican Catholics around the world.
