Christ:God and Man

Colossians 2:9 "For in him the whole fulness of the deity dwells bodily."

...Christ is God and man, but in such a way that this meeting of the divine and the human in him does not impose the slightest limitation anywhere. God is not in the least restricted by the Incarnation; it neither hinders nor weakens him; it does not put him in a state of unconsciousness; nothing is lacking to him of his divinity, his eternal life and omniscience. But nothing is lacking to Christ the man, either, as a result of his being God; he does not run up against his divinity as though encountering an obstacle to his genuine, full humanity; it is not as though he skipped right over finite human feelings, knowledge and experience and rushed like a stream into his divinity, finding therein a support for his existence that is unavailable as such to any other man. Rather, he is God and man in a union that leaves both natures intact and binds them together in their perfection, not making them merely run side by side. Only such a union can bring it about that in him the whole fulness of the deity dwells bodily, that deity actually accompanies this human life and has a share in this genuine human experience...Divinity and humanity are so intimately bound together in his being that they interpenetrate, with the exception of only those places where the fulness of one would constrain the fulness of the other and would cause harm to it. Aside from that, the two live in one another in a perfect vitality; God takes on perfectly the man united with him, and he who was made man is permitted to live in God.
