Book excerpt: In the early books of the Old Testament, the mysterious "Angel of the Lord" repeatedly appears-visibly, audibly, even physically-to the Patriarchs, to Moses, to the Prophets. Who is this Angel? Exploring the biblical texts, the testimony of church history, and the insights of Systematic Theology, Matt Foreman and Doug Van Dorn argue that the answer is beyond doubt: the Angel of the Lord is a manifestation of God the Son. Even more, they argue that this Angel appears more often than people realize, because he appears under different titles, including: the Word, the Name, the Glory, the Face, the Right Hand, even the Son. They show that even some of the ancient Jews spoke of a Second Yahweh in the Old Testament. Christian theologians throughout history have taught this same understanding. Christians today need to be taught again how the Person of Jesus appears throughout the Bible and how he speaks to us today.
