According to the opening lines of the Confession (1689.1.1, Of The Holy Scriptures), Scripture is the only sufficiency. Before speaking of its certainty and infallibility, the authors communicated sufficiency. And also this entire opening phrase in the 1689 is not in the the Westminster Confession. Well, how interesting!  I like this. Here is an immediate statement about the Word of God – what it is. It makes sense because the phrase beginning with “although” (see Westminster) should follow some introductory clause. And so we have the 1689’s opening lines. How beautiful and right.
