Westminster Confession of Faith
Chapter 1: Of the Holy Scripture
7: All things in Scripture are not alike plain in themselves, nor alike clear unto all:[15] yet those things which are necessary to be known, believed, and observed for salvation are so clearly propounded, and opened in some place of Scripture or other, that not only the learned, but the unlearned, in a due use of the ordinary means, may attain unto a sufficient understanding of them.[16]
