Augustine didn’t write it:
“Written by Bishop Fulbert of Chartres (ca 951-ca 1029), it appears in his Sermo IX, De Annuntiatione Dominica. The prayer is sometimes attributed to St. Augustine, Book 10, Sermon 18, de Sanctis, since Bishop Fulbert’s sermon appeared in the collected works of St. Augustine at one time. However, it is now known that the sermon is not Augustine’s, but Bishop Fulbert’s.”
