Erasmus is said to have replied to his critics that the comma did not occur in any of the Greek manuscripts he could find, but that he would add it to future editions if it appeared in a single Greek manuscript. Such a manuscript was subsequently produced, some say concocted, by a Franciscan, and Erasmus, true to his word, added the comma to his 1522 edition, but with a lengthy footnote setting out his suspicion that the manuscript had been prepared expressly to confute him. This change was accepted into editions based on the Textus Receptus, the chief source for the King James Version, thereby fixing the comma firmly in the English-language scriptures for centuries. There is no explicit evidence, however, that such a promise was ever made.
