You may find members of Presbyterian and Reformed churches more theologically engaged than usual these days. This year marks the 500th anniversary of John Calvin’s birth. I decided to observe the occasion by focusing my reading this summer on Calvin. I skimmed T. H. L. Parker’s classic biography, which I had read years before. I read Bruce Gordon’s new and exceptional biography, Calvin; William Stacy Johnson’s John Calvin: Reformer for the 21st Century; the commemorative issue of Theology Today; and a surprisingly lucid Calvin for Armchair Theologians, by Christopher Elwood.
