St. Boniface, Bishop and Martyr
Made a legate of the Apostolic See by Gregory II, he called together several synods, among which was the famous Council of Leptines in the diocese of Cambrai. Appointed archbishop of Mainz by Pope Zachary, he, by his order, anointed Pepin king of the Franks.
After the death of St. Willibrord, the Church of Utrecht in Frisia was committed to his care. The Frisians massacred him at Dokkum with thirty of his monks, in June 755. His body was buried in the celebrated abbey of Fulda which he had founded.
Exsultabo in Jerusalem, et gaudebo in populo meo: et non audietur in eo ultra vox fletus et vox clamoris. Electi mei non laborabunt frustra, neque generabunt in conturbatione: quia semen benedictorum Domini est, et nepotes eorum cum eis. Alleluia, alleluia. * Deus, auribus nostris audivimus: patres nostri narraverunt opus, quod operatus es in diebus eorum.
I will rejoice in Jerusalem, and joy in My people, and the voice of weeping shall no more be heard in her, nor the voice of crying. My elect shall not labour in vain, nor bring forth in trouble: for they are the seed of the blessed of the Lord, and their posterity with them. Alleluia, alleluia. * We have heard, O God, with our ears: our fathers have declared the work Thou hast wrought in their days.
(Isaias 65:19,23 and Psalm 43:2 from the Introit of Mass)
Deus, qui multitudinem populorum, beati Bonifatii Martyris tui atque Pontificis zelo, ad agnitionem tui nominis vocare dignatus es: concede propitius; ut, cujus solemnia colimus, etiam patrocinia sentiamus.
O God, who didst vouchsafe by the zeal of blessed Boniface, Thy martyr and bishop, to call a great multitude of peoples to the knowledge of Thy name; grant in Thy mercy, that we who keep this festival day, may also enjoy his protection.
