I. The Personal Union (p. 85 et.seq.)
1. In Christ, God and man are united in one Person.
2. His human nature:
a. Created in the time appointed by God.

3. The resulting and singular union of God and man into one Person is called the personal union.
a. Term used to clearly and unmistakably express this truth.
b. In Christ, God and man:
(1) Do not form any kind of union in general.
(2) But, constitutes a personal unity.
B. “Other” unions
1. The union of God with all creatures.
a. Jer 23:24: refers to His essence, not merely His activity.

C. Uniqueness of the personal union.
1. Important to hold fast the uniqueness of this.
2. There is no analogy in all creation comparable to it.
3. May be likened to:
a. Union of body and soul in man (e.g. Col 2:9; Athanasian Creed).
b. Union of fire and union in the glowing iron (e.g. ancient teachers; Formula of Concord, Epit. VIII, 9)
c. But we can not say the soul is the body or fire is iron.
d. We can say “God is Man, and Man is God”.
4. Personal prepositions are unique.

(2) Hos 11:9.
(3) 1Sa 15:29.

(5) Lk 2:51 (by His subjection to His earthly parents, shows His consciousness of His human estate).
E. The Personal Union has not met with the approval of men.
1. Always looking for substitutes.
2. But, the Christian Church has always rejected such substitutes.
a. Against Eutyches: Church rejected every fusion and conversion of God and man.
b. Against Nestorius: Church rejected any union after manner of that between God and all creatures or with the believers.
c. Every intermingling of the two natures with a third as its necessary result rejected.
