St Gabriel the Archangel announced Blessed Virgin Mary that she has to become a Mother of the Son of God. We read this prayer three times a day: morning, noon and evening. In Easter Time, instead of the Angelus, we pray Queen of Heaven (Regina Caeli). 

℣: The Angel of the Lord declared unto Mary,
℟: And she conceived of the Holy Spirit.
Hail Mary…

℣: Behold the handmaid of the Lord,
℟: Be it done unto me according to your 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 you, O Lord, your grace into our hearts: * that we, to whom the Incarnation of Christ your 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.

Glory be to the Father…

℣: Eternal rest grant unto them, O Lord,
℟: And let perpetual light shine upon them.
℣: May they rest in peace.
℟: Amen.
