The Church of Rome, notwithstanding her pretensions to infallibility, has been fully as prolific in theological controversy and intestine discord as any of the Reformed Churches. She has contrived, indeed, with singular policy, to preserve, amidst all her variations, the semblance of unity. Protestantism, like the primitive Church, suffered its dissentients to fly off into hostile or independent communions. The Papacy, on the contrary, has managed to retain hers within the outward pale of her fellowship, by the institution of various religious orders, which have served as safety-valves for exuberant zeal, and which, though often hostile to each other, have remained attached to the mother Church, and even proved her most efficient supporters. Still, at different times, storms have arisen within the Romish Church, which could be quelled neither by the infallibility of popes nor the authority of councils. It is doubtful if religious controversy ever raged with so much violence in the Reformed Church, as it did between the Thomists and the Scotists, the Dominicans and Franciscans, the Jesuits and the Jansenists, of the Church of Rome.
