Vows belong to the Lord alone, not to Saints as gods by participation or as obtainers of goods
Vows, Scripture says, are to be made and paid to the Lord alone.
To vow to Saints as gods by participation, or as those who obtain what we need, is as contrary to true piety as offering them sacrifices under the same title.
Latin
XXVIII. Idem sentiunt de votis, quae Scriptura Domino soli concipi & exsolvi jubet, nec putant minus a vera pietate abhorrere, ut quis voveat Sanctis, quatenus sunt Dii quidam per participationem, vel impetratores bonorum quibus egemus, quam ut quis sub eodem titulo iis offerat sacrificia & victimas.
