Ridley, Latimer, And Cranmer: The Oxford Martyrs

What I Learned From Polycarp About Pearls, Swine, And Modern Evangelicals

In the fall semester I teach two courses on the ancient church. One is a seminar in which we read the Apostolic Fathers (a somewhat arbitrary collection of texts from the second century) as well as other important writers from the period. . . . Continue reading →

Why Do Good Men Approve Of Bad Texts?
