"Love is the source of righteousness in the heart, a port of understanding, rivers of water for life, and knowing the secrets of both the known and unknown worlds. Love is a language understood by the angels." (St. John Saba, the Spiritual Elder)
The Old Testament records that mankind had fallen, and been driven out of paradise; but God in His continuing love, desired to restore man to his original state. Ezekiel the prophet and priest prophesied this great, everlasting, restorative love of God for his people in spite of their rebellion for which they had deserved to be exiled, and their temple to be destroyed. Jerusalem, at the time, "her nativity was from the land of Canaan and her father was an Amorite and her mother a Hittite" (Ezekiel 16:3) had been entirely unfaithful to God. That was the status of God’s relationship with Jerusalem and, symbolically, all of Israel.
"When I passed by you again and looked upon you, indeed your time was the time of love; so I spread My wing over you and covered your nakedness. Yes, I swore an oath to you and entered into a covenant with you, and you became Mine, says the Lord God" (Ezekiel 16:8).
With these prophetic words, God reinstates His inexhaustible love despite Israel’s immoral and idolatrous life; and in so doing, He describes an Old Covenant relationship to the one Jerusalem He was to be forever faithful unto.
However, man’s restoration to his original pure state he was created in, was practically inconceivable. For, how could the establishment of such an eternally necessary, yet lost condition for man's soul be achieved? Nevertheless, God defied the inconceivable with the only one answer: the Incarnation of the Son of God, the Second Person of the Holy Trinity. The Lord Jesus Christ must take upon Himself a complete human body through which, on behalf of man's evil ways, He would pay the punishment of death man himself should have paid. So great was man’s intent disobedience; and consequently, so great the price.
This heavenly mandate is profoundly expressed in a Letter to Diognetus (c. 125-200),
"Truly God Himself, who is Almighty, the Creator of all things, and invisible, has sent from Heaven, and placed among men, the One who is the Truth, and the Holy and Incomprehensible Word... God did not, as one might have imagined, send to men any servant, angel, or ruler…Rather, He sent the very Creator and Fashioner of all things—by whom He made the Heavens... As a king sends his son, who is also a king, so God sent Him. He sent Him as God."
But before the Lord Jesus Christ was to painfully pay for our sins; He would come to show us a real, true, and complete love. The Apostle St. Paul refers to this love as "a more excellent way" (I Corinthians 12:31). A new and lasting covenant would be brought about.
The Glorious Nativity was and continues to be a limitless, timeless measure of God's unceasing love for mankind.
God's unbound love honors man; because firstly, God created man in "His image and according to His likeness" (Genesis 1:27). Secondly, He Himself became a living, earthly human being. Thus, The Nativity has forever established for and imprinted upon us all the presence of God's perfect love. The creation of the entire world did not extract from God anything other than "Let it be done and it was done". So mankind was capable of treasuring creation at no cost at all; neither to nor from God. That is why God's redeeming love for the world He had created, its very salvation, had dearly cost Him to come down from Heaven and take upon Him the mundane nuisance and trials of human existence. And the cost, we all know, did not stop there...
Through God's love, the Glorious Nativity heralded the foundation of man's redemption.
The Ante-Nicene Father, Irenaeus (c. 180) wrote:
"Thus He indicates in clear terms that He is God, and that His Advent was in Bethlehem…God then, was made man, and the Lord did Himself save us."
