"O God, strength of those who hope in you, graciously hear our pleas, and, since without you mortal frailty can do nothing, grant us always the help of your grace, that in following your commands we may please you by our resolve and our deeds.  Through."

"Deus, in te sperantium fortitudo, invocationibus nostris adesto propitius, et, quia sine te nihil potest mortalis infirmitas, gratiae tuae praesta semper auxilium, ut, in exsequendis mandatis tuis, et voluntate tibi et actione placeamus.  Per."

This (which lacks the semper added to it after Vatican II) is present in the mid 8th century Old Gelasian (Rome, Vatic. Reg. Lat. 316, 88r; Mohlberg, Eizenhöfer, & Sifrin, eds.

(Oxford, 1894) no. 587), as well as a couple of other 8th-century sacramentaries (Gellon., Rhen.); and, although Corpus orationum doesn't mention this, in the Gregorian (Hadrianum), which was copied from an earlier Roman original in 811-812 (Deshusses, Le sacramentaire Grégorien (Fribourg, 1992) no. 1129 (vol. 1, 3rd. ed., p. 390; also nos. 595, 1964, etc.).

"the modern view combining relativism and progress . . . is incoherent."

IVP

"the modern view combining relativism and progress as widely understood is incoherent.  A true relativism would assume that no worldview is better than another; a true progressivism would assume that worldviews are moving closer and closer to a predetermined and preferred goal.  The two beliefs are mutually exclusive.  The assumption of the superiority of 'our' views to that of older cultures is the most stubborn remaining variety of ethnocentrism."
