Thankfully, I only read excerpts of "Institutes" as part of the huge Great Books set I got from my wife's grandmother: https://www.amazon.com/Foundation-readings-discussion-course-volumes/dp/B000N83EWU .. I've been slowly working through these classics and mostly enjoying every one, but John Calvin seemed to be one of the hardest to slog through. My general impression of Calvin is that he was very rigid and closed-minded. He acknowledges that there are smart and wise people on earth who aren't christian, but then goes ahead and says that you basically have to be a christian in order to gain any knowledge in this world and that everybody else is stupid... Maybe it was my attitude going into this, but I don't think I want to delve any deeper into Calvin's writings. I already knew I didn't like Hobbes. Who knew I would dislike both Calvin and Hobbes?
