One piece is a brief but helpful biography and the other is a look at good and the not so good of Kuyper's legacy. Not all would agree that common grace is one of the not so good aspects of Kuyper's work.
A new translation of Kuyper's The Cross Versus the Tree of Liberty by Jan Boer is now available at CCEL. It was originally a lecture delivered at the opening of the tenth annual meeting of the
Anti-Revolutionary Party during the centennial of the French Revolution (1889.07)
