Equally amazing to the doctrine of the Trinity is the doctrine of the Incarnation--that Jesus Christ is God and man, yet one person, forever. As J.I. Packer has said: "Here are two mysteries for the price of one--the plurality of persons within the unity of God, and the union of Godhead and manhood in the person of Jesus. ...Nothing in fiction is so fantastic as is this truth of the Incarnation," writes contemporary theologian J.I. Packer.1

The early church considered the Incarnation to be one of the most important truths of our faith. Because of this, they formulated what has come to be called the Chalcedonean Creed, a statement which sets forth very what we are to believe and what we are not to believe about the Incarnation. This creed was the fruit of a large council that took place from October 8 to November 1, 451, in the city of Chalcedon and "has been taken as the standard, orthodox definition of the biblical teaching on the person of Christ since that day by" all the major branches of Christianity.2 There are five main truths with which the creed of Chalcedon summarized the biblical teaching on the Incarnation.
