When Pilgrim misspoke, he actually articulated the true doctrine of the Reformed Church. The Reformed accept the words, "one person and subsistence" of the Chalcedon Creed but deny its meaning. Pilgrim even contends that the Son of God and the Son of Man are physically separate beings contrary to Chalcedon, "not as parted or separated into two persons."
The Reformed also misunderstand the Chalcedon "without confusion, without change, without division, without separation; the distinction of natures being in no way annulled by the union, but rather the characteristics of each nature being preserved". The characteristics of each nature are preserved and are never mingled, changed, or confused with the other nature.
However, that does not mean there is no communication of the attributes. The Lutheran Concordists use the analogy of iron being heated in a fire. The heat is communicated to the iron but the iron does not give up any of the properties of iron and heat remains a property of the fire. So the characteristics of each nature are preserved without change, division or separation.
If Christ lived, suffered, and died only as a man as the Reform propose, He would be a poor Savior. He would be unable conquer sin, death, and the Devil and atone for the infinite offense of the world of sin and sinners. But, in Him dwells all fulness of the Godhead bodily. He has all power and all knowledge, is always present as He has promised, and His Holy precious blood cleanses us from all sin.
