There are other meanings as well which cast doubt on the authenticity of the story (not surprising actually when you consider the Bible's Apocrypha's relationship with the Church.) Here are the 2 definition OED gives:
1. A writing or statement of doubtful authorship or authenticity; spec. those books included in the Septuagint and Vulgate versions of the Old Testament, which were not originally written in Hebrew and not counted genuine by Jews, and which, at the Reformation, were excluded from the Sacred Canon by the Protestant party, as having no well-grounded claim to inspired authorship.
2. [As in Greek] Hidden things; secrets. rare.
