Easton's 1897 Bible Dictionary:

Incarnation
   that act of grace whereby Christ took our human nature into
   union with his Divine Person, became man. Christ is both God and
   man. Human attributes and actions are predicated of him, and he
   of whom they are predicated is God. A Divine Person was united
   to a human nature (Acts 20:28; Rom. 8:32; 1 Cor. 2:8; Heb.
   2:11-14; 1 Tim. 3:16; Gal. 4:4, etc.). The union is
   hypostatical, i.e., is personal; the two natures are not mixed
   or confounded, and it is perpetual.
