I would not recommend this volume as the first thing to read by Van Til. I would recommend it to be one of the last. It is not without merit, of course. Van Til repeats and alludes to a lot of earlier works and more often than not he doesn’t fully develop his thoughts. Here are the high points:
He posits the Reformed Pastor-Evangelist as the one who presupposes the self-contained Ontological Trinity who speaks in history. I agree with him. Aside from a few page-long quotations from Calvin, he doesn’t develop this argument. He does develop it in detail in *Introduction to Systematic theology.* He then has the famous Mr Grey, Mr White, Mr black conversation.
Then he gives the shortcomings of Arminian and Roman Catholic apologetics. This is disappointing. He is always on the verge of “nailing the case shut,” and then the chapter or section ends abruptly. It is doubly frustrating because he is making good and incisive points, but they are not connected.
He gives an outstanding analysis of Paul Tillich (which is fleshed out and developed) and a fine critique, if too brief, of the Ecumenical Movement.
By all means read this volume. Just don’t read it first.
