"while in this body we not only experience the daily effects of your care, but even now possess the pledge of life eternal."

"atque in hoc corpore constituti non solum pietatis tuae cotidianos experimur effectus, sed aeternitatis etiam pignora iam tenemus."

     Preface VI of the Sundays in Ordinary Time, Missale Romanum, from the 8th century Prague sacramentary.  (According to Ward & Johnson, "tuae . . . pietatis effectus" appears also in the Gelasian sacramentary.)
