Therefore, O Lord,we pray you that this candle, hallowed to the honour of your name, may persevere undimmed, to overcome the darkness of this night. Receive it as a pleasing fragrance, and let it mingle with the lights of heaven. May this flame be found still burning by the Morning Star: the one Morning Star who never sets, Christ your Son, who, coming back from death’s domain, has shed his peaceful light on humanity, [with you or in agreement with you] and lives and reigns for ever and ever. Amen.The addition is a vocative cue to the ecclesia to be ready to sing Amen.Apart from that the words are exactly as per the official Latin as quoted and therefore are as the official English as quoted.
