The question of which is the "official text" of the "Apology" arises in connection with the English translation of the text in the 2000 "Kolb-Wengert Edition" of "The Book of Concord". The translators and editors of this edition made the octavo edition the main source for their English translation because they believe it to be the "'official' version" of "The Apology". They included English translations of variant readings of the quarto edition in italics. Scholars question whether this text could be the actual Lutheran confession, especially since it was the quarto edition that was deliberately included in the 1584 official Latin "Book of Concord" to the exclusion of the octavo edition. All other English translations of "The Book of Concord" utilize the quarto edition.
