O God, who by the lowliness of thy Son hast raised a fallen world: Grant to thy faithful people perpetual gladness; and as thou hast delivered them from eternal death, so do thou make them partakers of everlasting joys; through the same Jesus Christ our Lord.
8th-century Gelasian sacramentary (no. 541):
“Deus, qui in filii tui humilitate iacentem mundum erexisti, laetitiam concede fidelibus tuis, ut, quos perpetuae mortis eripuisti casibus, gaudiis facias sempiternis perfrui.”
