Douglas Kelly writes
"I have written this first volume, thinking of my heritage as both Reformed and Catholic; gladly appropriating crucial insights of the whole people of God over the last two thousand years - Eastern Orthodox, Western Catholic, and Reformation Protestant - as they sought to live out the foundational truths of the inspired Word of God."
Ligon Duncan has written these words about this volume: "Douglas F. Kelly is one of the English-speaking world's leading Reformed theologians. Here we begin to enjoy the fruits of his labors. What a feast it is. Few Protestant theologians in our day know the terrain of the doctrine of the Trinity, and the Person of Christ, as well as Professor Kelly... He is at his best when opening up to us the unrealized importance and glory of these foundational truths about our Savior God. For those who yearn for an orthodox Reformed catholicity, Kelly shows the way forward."
