By the first half of the 18th century, the Authorized Version was effectively unchallenged as the sole English translation in current use in Protestant churches, and was so dominant that the Roman Catholic Church in England issued in 1750 a revision of the 1610 "Douay-Rheims Bible" by Richard Challoner that was very much closer to the Authorized Version than to the original. However, general standards of spelling, punctuation, typesetting, capitalization and grammar had changed radically in the 100 years since the first edition of the Authorized Version, and all printers in the market were introducing continual piecemeal changes to their Bible texts to bring them into line with current practice—and with public expectations of standardized spelling and grammatical construction.
