SCRIPTURE COMMENTARY #10
THE ANGELUS: Besides the Hail Mary, thrice repeated, the Angelus contains:
1. the message of the angel;
2. the consent of Mary;
3. the result of her consent, namely, the Incarnation of the Son of God.
It therefore reminds us of the beginning of our Redemption and on the part Mary had in it. The words which it contains and which are repeated by us three times every day, are more important, more significant and more precious than any other words that human lips can utter, with the exception of the "Our Father."
