Since the thirteenth century, the Regina Cæli has been used as the seasonal antiphon in honour of the Blessed Virgin after Night Prayer, and since 1743 it has replaced the Angelus in the Easter Season.
Queen of heaven, rejoice. Alleluia:
For he whom you did merit to bear. Alleluia.
Has risen, as he said. Alleluia.
Pray for us to God. Alleluia.
Rejoice and be glad, O Virgin Mary. Alleluia.
For the Lord has truly risen. Alleluia.
Let us pray:
O God, who gave joy to the world through the resurrection of your Son our Lord Jesus Christ, grant, we beseech you, that through the intercession of the Virgin Mary, his Mother, we may obtain the joys of everlasting life, though the same Christ our Lord. R. Amen.
Regína cæli, lætáre. Allelúia.
Quia quem meruísti portáre. Allelúia.
Resurréxit, sicut dixit. Allelúia.
Ora pro nobis, Deum. Allelúia.
Gaude et lætáre, Virgo María, Allelúia.
Quia surréxit Dominus vere. Allelúia.
Deus, qui per resurrectiónem Fílii tui, Dómini nostri Iesu Christi, mundum lætificáre dignátus es: præsta, quáesumus; ut, per eius Genitrícem Vírginem Maríam, pérpetuæ capiámus gáudia vitæ. Per eúndem Christum Dóminum nostrum. R. Amen.
