Alma Redemptoris Mater is one of the four seasonal Marian antiphons, with it being sung from Advent through Candlemas (Ave Regina Coelorum for Candlemas through Lent, Regina Coeli from Easter to Pentecost, and Salve Regina for ordinary time).
Alma Redemptoris Mater, quae pervia coeli Porta manes, et stella maris, sucurre cadenti, Surgere qui curat populo: tu quae genuisti, Natura mirante, tuum sanctum Genitorem, Virgo prius ac posterius, Gabrielis ab ore Sumens illud Ave, peccatorum miserere.
O loving Mother of our Redeemer, gate of heaven, star of the sea, Hasten to aid thy fallen people who strive to rise once more. Thou who brought forth thy holy Creator, all creation wond’ring, Yet remainest ever Virgin, taking from Gabriel’s lips that joyful “Hail!”: be merciful to us sinners.
