To celebrate John Calvin’s 500th birthday (and, I suppose, the annual “Hug a Calvinist” day), for today only the folks at desiringGod are reissuing a classic biography on John Calvin for $2. The bio, called Portrait of Calvin, was written by T.H.L. Parker and was first published in 1954. Here is where you can purchase the book, and for those who just can’t afford the $2 bill, here‘s where you can download the book for free.
