But Principle of Unity

Are there not those who say that unity between the separated Churches and the Catholic Church would be more easily achieved if the primacy of the Roman pontiff were done away with? We beg our separated brothers to consider the groundlessness of this opinion. Take away the sovereign Pontiff and the Catholic Church would no longer be catholic. Moreover, without the supreme, effective, and authoritative pastoral office of Peter the unity of Christ's Church would collapse. It would be vain to look for other principles of unity in place of the true one established by Christ Himself. As St. Jerome rightly observed: "There would be as many schisms in the Church as there are priests." ⁶⁵
