In Sacred Scripture
Hail Mary, full of grace, the Lord is with you.
Luke 1:28 "And coming to her, he said, "Hail, full of grace, the Lord is with you."
The Greek kecharitomene means favored by grace, graced. Its tense suggests a permanent state of being "highly favored," thus full of grace. Charity, the divine love within us, comes from the same root. God is infinite Goodness, infinite Love. Mary is perfect created goodness, filled to the limit of her finite being with grace or charity.
Blessed art thou among women
Luke 1:41-42a "When Elizabeth heard Mary's greeting, the infant leaped in her womb, and Elizabeth, filled with the holy Spirit, cried out in a loud voice and said, "Most blessed are you among women..."
Luke 1:48 "For he has looked upon his handmaid's lowliness; behold, from now on will all ages call me blessed."
Among all women is a way to say the highest/greatest etc. of a group in Semitic languages (these words would likely have been spoken in Aramaic). Mary is being called the greatest of all women, greater than Ruth, greater than Sarah, greater than EVE! Since Eve was created immaculate (without original sin), Mary must have been conceived immaculate. And, although Eve fell into sin by her own free will, Mary must have corresponded to God's grace and remained sinless. She could not otherwise be greater than Eve. Thus, as the Fathers of the Church unanimously assert, Mary is the New Eve who restores womanhood to God's original intention and cooperates with the New Adam, her Son, for the Redemption of the world.
Blessed is the fruit of your womb, Jesus
Luke 1:42b "and blessed is the fruit of your womb."
Jesus is Mary's fruit. Good fruit does not come from anything but a good tree (Mt. 7:17-18)! The all-holy Son of God could not be the fruit of any other tree than the Immaculate Virgin.
Holy Mary, Mother of God
Luke 1:43 "And how does this happen to me, that the mother of my Lord should come to me?
Kyrios is the Greek word used by the Jews in the Septuagint Bible (Greek translation) for Yhwh, the Divine Name of God. In her greeting of Mary, Elizabeth is saying: "How is it that the mother of my God should come to me." Against the heresies of the 4th and 5th centuries which tried to split the Person of Jesus into two, divine and human, denying one or the other, the Council of Ephesus in 431 AD proclaimed Mary Theotokos (God-bearer, i.e. mother of God). Jesus is a single Person, a Divine Person, the 2nd Person of the Most Holy Trinity. To be mother of the Person Jesus is to be mother of a Person who is God. Mary's title protects this truth against errors which emphasize or deny, either the divinity or humanity of the Lord.
Pray for us sinners, now and at the hour of our death. Amen.
Luke 2:35 "...and you yourself a sword will pierce so that the thoughts of many hearts may be revealed."
John 2:5 "His mother said to the servers, "Do whatever he tells you."
Mary sees a need and appeals to Her Son to satisfy it. He does. We turn to Mary to ask her to intercede with her Son in our daily spiritual and material needs, but especially at the hour of our death. At that moment our salvation hangs in the balance as the devil makes his final foray to deter us from the path to God (Rev. 2:10). It is not surprising, therefore, that both the Hail Mary and the Our Father conclude with an appeal to be delivered from the evil one.
The Power of Intercessory Prayer:
Intercessory prayer proceeds from faith in God that holy men and women who have died are as alive today as they were on earth (Luke 20:38). If the prayer of the just man avails much, how much more the prayer of the one made perfect (Rev. 21:27) and living with God in heaven (the patriarchs, apostles and other holy men and women).
James 5:16b "the fervent prayer of a righteous man is very powerful."
Rev. 5:8 "When he took it, the four living creatures and the twenty-four elders fell down before the Lamb. Each of the elders held a harp and gold bowls filled with incense, which are the prayers of the holy ones.
The angels, too, mediate our prayers. This is taught explicitly in the Jewish book of Tobit (Tob. 12:12), accepted by Christians as inspired until Luther on his own authority rejected it. It remains part of the Catholic Bible.
Tobit 12:12 I can now tell you that when you, Tobit, and Sarah prayed, it was I who presented and read the record of your prayer before the Glory of the Lord; and I did the same thing when you used to bury the dead.
Rev. 8:3 "Another angel came and stood at the altar, holding a gold censer. He was given a great quantity of incense to offer, along with the prayers of all the holy ones, on the gold altar that was before the throne."
Is the rosary mindless babbling?
The purpose of the different beads on the rosary is to count the various prayers as they are said. Unlike the Moslem prayer beads and the mantras of Buddhism, the prayers of the rosary are meant to occupy our whole being, body and soul, while meditating on the truths of the Faith. Any prayer is vain, however, if said mechanically without devotion. Simply to repeat prayers is not the vain repetition condemned by Christ (Mt 6:7), since He Himself repeats His prayer in the Garden three times (Mt 26:39, 42, 44) and the Psalms (inspired by the Holy Spirit) are often very repetitive (Ps 119 has 176 verses and Ps. 136 repeats the same phrase 26 times).
Matthew 6:7 In praying, do not babble like the pagans, who think that they will be heard because of their many words.
Praise the LORD, who is so good;
God's love endures forever;
Praise the God of gods;
God's love endures forever;
. . . Praise the God of heaven,
God's love endures forever.
Matthew 26:39 He advanced a little and fell prostrate in prayer, saying, "My Father, if it is possible, let this cup pass from me; yet, not as I will, but as you will."
Matthew 26:42 Withdrawing a second time, he prayed again, "My Father, if it is not possible that this cup pass without my drinking it, your will be done!"
Matthew 26:44 He left them and withdrew again and prayed a third time, saying the same thing again.
The Church believes that it is necessary for a Christian to meditate (prayerfully think about) the will of God, the life and teachings of Jesus, the price He paid for our salvation, and so on. Unless we do this we will begin to take these great gifts for granted and ultimately fall away from the Lord. Every Christian must meditate in some way in order to preserve the gift of salvation (James 1:22-25). Many Catholic and non-Catholic Christians prayerfully read and apply Scripture to their lives, that is, meditate on them. With the rosary this can be done virtually anywhere and anytime.
