So I conclude the statement is correct, although more of a paraphrase (like the “Rome has spoken, the case is closed” summary of Augustine, Sermons 131:10) depending on the accuracy of translation. Here is Jurgens translation:
“…they dare even to set sail…to the chair of Peter and the principal Church [at Rome], in which sacerdotal unity has its source…whose faith was praised by the preaching Apostle, and among whom it is not possible for perfidy [errors or perversion of faith] to have entrance.” (Epistle 59:14)
Here’s another translation from Edward Giles (an Anglican historian), the original Latin is from John Chapman:
Post ista adhuc pseudoepiscopo sibi ab haereticis constituto nauigare audent, et ad Petri Cathedram adque ad ecclesiam principalem unde unitas sacerdotalis exorta est ab schismaticis et profanis litteras ferre, nec cogitare eos esse Romanos, quorum fides Apostolo praedicante laudata est, ad quos perfidia habere non possit accessum
Translated this means, according to the Anglican scholar Giles:
“After all this, they yet in addition, having had a false bishop ordained for them by heretics, dare to set sail, and to carry letters from schismatic and profane persons to the chair of Peter, and to the principal church, whence the unity of the priesthood [sacerdotal unity] took its rise [or has its source]. They fail to reflect that those Romans are the same as those whose faith was publicly praised by the apostle, to whom unbelief [or error, heresy, perversion of faith] cannot have access.” (Epistle 59:14; from Giles, Documents Illustrating Papal Authority, page 60)
