Discussions about the history of the reception of the Apocrypha within Protestantism are often mired by blanket negative presumptions that differ markedly from the actual beliefs attested to in available historical sources. This chapter seeks to rectify such historical misrepresentations by presenting an initial attempt to summarize the entire history of Protestant thinking about the issue from the beginning of the Protestant Reformation to the start of the twentieth century with Seventh-day Adventism. In distinction from most popular representations about the issue, it is argued that Protestants, on the whole, did not reject the Apocrypha as inspired, even as they debated the merits of individual books within it as candidates for Scripture. Special attention is given to Martin Luther’s own thinking about the canon and clarifying what his intentions were for placing the apocryphal books in their own section, arguing that his decision was not envisioned by him as final nor his own desire. Due to the fact that most modern Protestant creeds do not explicitly reject the Apocrypha as inspired or define what books make up the canon they refer to when speaking of the “Old Testament” (nor did many of their spiritual forebears), it is concluded that it must be acknowledged that for many Protestants, the Old Testament canon has not been formally closed since the Reformation began.
