Rerum, Deus, tenax vigor (O Strength and Stay upholding all creation)
O Strength and Stay upholding all creation Who ever dost Thyself unmoved abide, yet day by day the light in due gradation from hour to hour though all its changes guide; Grant to life's day a calm unclouded ending, an eve untouched by shadows of decay, the brightness of a holy deathbed blending with dawning glories of the eternal day. Hear us, O Father, gracious and forgiving, and Thou, O Christ, the coeternal Word, Who, with the Holy Ghost by all things living, now and to endless ages art adored. Amen.
