On the morning of Holy Saturday 1884, Kuyper wrote the promised letter to Professor Harting (see 1884.04) contrasting the rationalistic, liberal worldview and the Christian vision of life. This very extensive letter—at once both critical and respectful of Prof. Harting—expresses Kuyper’s personal vision of what is essential to the Christian worldview.
