I beg that all those into whose hands my book may fall will lay aside all preconceived opinion and put the truth to the test. For clearness’ sake I will divide my book into three dialogues. The first will contain the contention that the Godhead of the only-begotten Son is immutable. The second will by God’s help show that the union of the Godhead and the manhood of the Lord Christ is without confusion. The third will contend for the impassibility of the divinity of our saviour. After these three disputations we will subjoin several others as it were to complete them, giving formal proof under each head, and making it perfectly plain that the apostles’ doctrine is preserved by us.
