Hmmm... I'm curious.
Do you realize that this op is specifically, and exclusively, about Calvin's "Institutes of the Christian Religion"? Do you the thread is not about Calvin's theology as a whole, Beeke, MacArthur, Sproul, or Non-Baptist Reformed? Do you realize that in the space of five single-statement posts the original topic has been ignored.
Calvin's "Insititutes..." is not representative of his larger theology. This is a common misconception regarding Calvin and Calvinism. Calvin set out writing The Institutes in an effort to reform Catholicism, not establish a systematic theology. The Institutes was originally only six chapters in length. It grew in length and diversity of content as Calvin aged, left the RCC, and began addressing other religious/theological matters. Even in its final edition, at 80 chapters, it does not express Calvin's theology anywhere near as well as his commentaries (which cover at least 50 of the Bible's 66 books). Calvin was a prolific writers and substantive exegete. His "Institutes...." is important primarily for its historical value as both a seminal work in religious writing, and as a turning point in Christian thought. For those reasons, it stands on its own. It does not stand on its own as an exposition of Calvin's larger theology.
