Redaction critics tend to favor a view that biblical books were written much later and by different authors than the text relates. Late theological editors attached names out of history to their works for the sake of prestige and credibility. In Old and New Testament studies this view arose from historical criticism, source criticism, and form criticism. As a result, it adopts many of the same presuppositions, including the documentary hypothesis in the Old Testament and the priority of Mark in the New Testament. A redactor edits or changes a text composed by another. Redaction criticism of the Bible claims that subsequent editors (redactors) changed the text of Scripture. If such alleged changes were substantial, it would seriously damage the credibility of Scripture. We could not be sure what was in the original text.
