At a convocation of the bishops and other dignitaries of the Church of England, 1870, it was decided to revise the King James (the Authorized) Version of the Bible, which had been made in 1611.
The intervening two centuries and a half had seen a considerable advance in scholarly study of the original text; moreover, numerous expressions in the Authorized Version had become archaic.
In 1885 the Revised Version was published.
It is written in a more readable English style and is a more accurate translation than the Authorized Version.
Cooperating with the English Revision Committee was an American Committee.
The changes proposed by the latter were incorporated in an American Revised Version, published in 1901.
This is called the American Standard Version.
