"The oath at present required by law is, "That the sacrifice of the mass, and the invocation of the blessed Virgin Mary, and other saints, as now practised in the Church of Rome, are impious and idolatrous." Of course I will never stain my soul with such an oath: I leave that to my honourable opponent, Mr. Vesey Fitzgerald. He has often taken that horrible oath; he is ready to take it again, and asks your votes, to enable him so to swear. I would rather be torn limb from limb than take it... Return me to parliament, and it is probable that such blasphemous oath will be abolished for ever."
