"I acknowledge the holy, catholic, apostolic and Roman church, the mother and mistress of *all the churches. Likewise all other things which have been transmitted, defined and declared by the sacred canons and the ecumenical councils, especially the sacred Trent, I accept unhesitatingly and profess; in the same way whatever
is to the contrary, and whatever heresies have been condemned, rejected and anathematised by the church, I too condemn, reject and anathematise. This true catholic faith, outside of which none can be saved, which I now freely profess and truly
hold, is what I shall steadfastly maintain and confess, by the help of God, in all its completeness and purity until my dying breath, and I shall do my best to ensure that all others do the same. This is what I, the same Pius, promise, vow and swear. So help
me God and these holy gospels of God."
