The Angelus (Latin for "angel") is a Traditional Catholic devotion commemorating the Incarnation.  The devotion was traditionally recited in churches, convents, and monasteries three times daily: the morning, noon, and evening (many churches still follow the devotion, and many practise it at home.) The Angelus is usually accompanied by the ringing of the Angelus bell, which is a call to prayer and to spread good-will to everyone.

The Angel of the Lord declared to Mary: 
And she conceived of the Holy Spirit. 

Hail Mary, full of grace, the Lord is with thee; blessed art thou among women and blessed is the fruit of thy womb, Jesus. Holy Mary, Mother of God, pray for us sinners, now and at the hour of
our death. Amen. 

Behold the handmaid of the Lord: Be it done unto me according to Thy word. 

Hail Mary . . . 

And the Word was made Flesh: And dwelt among us. 

Hail Mary . . . 

Pray for us, O Holy Mother of God, that we may be made worthy of the promises of Christ. 

Let us pray: 

Pour forth, we beseech Thee, O Lord, Thy grace into our hearts; that we, to whom the incarnation of Christ, Thy Son, was made known by the message of an angel, may by His Passion and Cross be brought to the glory of His Resurrection, through the same Christ Our Lord.

Amen.  

"Hail, full of grace, the Lord is with you" (Lk 1:28)

 and blessed is the fruit of your womb"
(Lk 1:42).
