"you . .. fashioned for us a remedy out of mortality itself, that the cause of our downfall might become the means of our salvation"

Piero della Francesca, c. 1463

"it belongs to your boundless glory, that you came to the aid of mortal beings with your divinity and even fashioned for us a remedy out of mortality itself, that the cause of our downfall might become the means of our salvation, through Christ our Lord."

"Ad cuius immensam gloriam pertinere . . . ut mortalibus tua deitate succurreres; sed et nobis provideres de ipsa mortalitate nostra remedium, et perditos quosque unde perierant, inde salvares, per Christum Dominum nostrum."

     Preface III of the Sundays in Ordinary Time, Missale Romanum.  This comes from the 7th (or even in some places 6th or 5th) -century Veronese (or "Leonine") sacramentary, no. 1115 = p. 141 in the 1956 edition of that ed. Mohlberg (which specifies also, among early sacramentaries, the Gelasian, the Gregorian, and the Ambrosian):

"ad cuius inmensam pertinet gloriam, ut non solum mortalibus tua deitate succurreris, sed de ipsa etiam mortalitate nostra nobis remedium prouideris, et perditos unde |:quo:| perierant, inde saluaris:  per."

This came out in the older "translation" of the new Missal as:

"You came to our rescue by your power as God, but you wanted us to be saved by one like us."
