The Lord Jesus Christ is God Himself, the Incarnate Logos.

Who took to Himself a perfect manhood. His Divine

nature is one with his human nature yet without mingling,

 confusion or alteration; a complete Hypostatic Union.

Words are inadequate to describe this union.

 It was said, that without controversy,

"Great is the mystery of godliness: God was manifested

in the flesh, (1 Tim. 3:16).

As this union is permanent, never divided nor separated,

we say in the liturgy that His Godhead never departed

from His manhood for a single moment nor even for a

 twinkle of an eye.

The Divine nature (God the Word) was united with

the human nature which He took of the Virgin Mary by the

action of the Holy Spirit. The Holy Spirit purified and

sanctified the Virgin's womb so that the Child to whom

she gave birth would inherit nothing of the original sin;

 the flesh formed of her blood was united with the

Only-Begotten Son. This unity took place from the

first moment of the Holy Pregnancy in the Virgin's womb.

As a result of the unity of both natures-the Divine and the

human-inside the Virgin's womb, one nature was formed out

of both: "The One Nature of God the Incarnate Logos" as St.

Cyril called it.

The Holy Church did not find an expression more

 reliable, deep and precise than that which was used

by St. Cyril the Great, and which St. Athanasius the

Apostolic used before him,

 as we have discussed this issue before here on st-takla.org

in other sections. Both of them were true leaders in the

 theological field worldwide.
