Even though there is nothing so great as the majesty of God and nothing so low as man insofar as he is a sinner, Almighty God does not despise our poor prayers. On the contrary, He is pleased when we sing His praises.
Saint Gabriel's greeting to Our Lady is one of the most beautiful hymns which we can possibly sing to the glory of the Most High. "I will sing a new song to you" (Ps. 143:9).
This new hymn which David foretold was to be sung at the coming of the Messiah is none other than the Angelic Salutation.
There is an old hymn and a new hymn: the first is that which the Jews sang out of gratitude to God for creating them and maintaining them in existence—for delivering them from captivity and leading them safely through the Red Sea—for giving them manna to eat and for all His other blessings.
The new hymn is that which Christians sing in thanksgiving for the graces of the Incarnation and the Redemption. As these marvels were brought about by the Angelic Salutation, so also do we repeat the same salutation to thank the Most Blessed Trinity for His immeasurable goodness to us.
We praise God the Father because He so loved the world that He gave us His only Son as our Savior. We bless the Son because He deigned to leave heaven and come down upon earth—because he was made man and redeemed us. We glorify the Holy Spirit because He formed Our Lord's pure Body in Our Lady's Womb—this Body which was the Victim of our sins. In this spirit of deep thankfulness should we, then, always say the Hail Mary, making acts of faith, hope, love and thanksgiving for the priceless gift of salvation.
Although this new hymn is in praise of the Mother of God and is sung directly to her, nevertheless it greatly glorifies the Most Blessed Trinity because any homage that we pay Our Lady returns inevitably to God Who is the cause of all her virtues and perfections. When we honor Our Lady: God the Father is glorified because we are honoring the most perfect of His creatures; God the Son is glorified because we are praising His most pure Mother, and God the Holy Spirit is glorified because we are lost in admiration at the graces with which He has filled His Spouse.
When we praise and bless Our Lady by saying the Angelic Salutation she always passes on these praises to Almighty God in the same way as she did when she was praised by Saint Elizabeth. The latter blessed her in her most elevated dignity as Mother of God and Our Lady immediately returned these praises to God by her beautiful Magnificat.
Just as the Angelic Salutation gives glory to the Blessed Trinity, it is also the very highest praise that we can give Our Lady.
One day when Saint Mechtilde was praying and was trying to think of some way in which she could express her love of the Blessed Mother better than she had done before, she fell into ecstasy. Our Lady appeared to her with the Angelic Salutation in flaming letters of gold upon her bosom and said to her:
My daughter, I want you to know that no one can please me more than by saying the salutation which the Most Adorable Trinity sent to me and by which He raised me to the dignity of Mother of God.
By the word Ave (which is the name Eve, Eva), I learned that in His infinite power God had preserved me from all sin and its attendant misery which the first woman had been subject to.
The name Mary which means "lady of light" shows that God has filled me with wisdom and light, like a shining star, to light up heaven and earth.
The words full of grace remind me that the Holy Spirit has showered so many graces upon me that I am able to give these graces in abundance to those who ask for them through me as Mediatrix.
When people say The Lord is with thee they renew the indescribable joy that was mine when the Eternal Word became incarnate in my womb.
When you say to me blessed art thou among women I praise Almighty God's divine mercy which lifted me to this exalted plane of happiness.
And at the words blessed is the fruit of thy womb, Jesus, the whole of heaven rejoices with me to see my Son Jesus Christ adored and glorified for having saved mankind.
