The incarnation — the eternal Logos taking on human nature without ceasing to be God. John 1:14: And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth. The Greek egeneto sarx (became flesh) is direct and shocking: the One who was God (1:1) became the kind of weakness God created. The verb eskēnōsen (dwelt) literally means tabernacled — placing His tent among us — echoing the tabernacle where the cloud of glory had dwelt (Ex 40:34). The incarnation is not God appearing as a man; it is God becoming truly Man, two natures permanently united in one Person, without confusion, without change, without division, without separation (Chalcedon, AD 451).
