In the Catholic Church … a few spiritual men attain [wisdom] in this life, in such a way that … they know it without any doubting, while the rest of the multitude finds [its] greatest safety not in lively understanding but in the simplicity of believing… [T]here are many other things which most properly can keep me in her bosom. The unanimity of peoples and nations keeps me here. Her authority, inaugurated in miracles, nourished by hope, augmented by love, and confirmed by her age, keeps me here. The succession of priests, from the very see of the apostle Peter, to whom the Lord, after his resurrection, gave the charge of feeding his sheep [John 21:15–17], up to the present episcopate, keeps me here.
And last, the very name Catholic, which, not without reason, belongs to this Church alone, in the face of so many heretics, so much so that, although all heretics want to be called “Catholic,” when a stranger inquires where the Catholic Church meets, none of the heretics would dare to point out his own basilica or house (*Against the Letter of Mani Called “The Foundation” *4:5 [A.D. 397])
