Novatian

“ Let us cherish the gratitude we owe to them for their good works, and use their testimony so far as it was faithful; covering their shame with the mantle of charity, and praying for grace never to imitate their faults. “If any teacher have wandered from the faith, it is permitted,” says St. Vincent of Lerins [1] , “by Divine Providence for our trial, whether we love God or not, with all our heart and with all our soul.”
We find Novatian apparently exercising jurisdiction, sede vacante, in Rome, with his co-presbyters, and as vicar-general (to use a later term) corresponding with Cyprian. ”

“ Cornelius was made bishop June 4, a.d. 251; and, apparently, disappointed ambition soon bore its thorny fruits. “Emulation of the episcopal office is the mother of schisms,” said Tertullian; [3] even in that period when to be a bishop was so often to be a martyr. And we find Novatian grasping a shadowy titular bishopric, which, wholly irregular and universally disowned, could have been to such a man the source of nothing but misery. I say, “to such a man,” for, without hearing the other side, I cannot accept what was unquestionably supposed to be fact amid the excitements of the times. ”

“ Now as to his orthodoxy, so far as his extant writings are concerned, I think any scholar, not anxious to make out a case, will abide by the candid judgment of Bull, who defends his reputation against Petavius. [5] “By no means,” he says, “should we tolerate that injustice of the Jesuit Petau towards the ancient writers, against their manifest mind and purpose; twisting, as he everywhere does, their sound and Catholic sayings into a sense alien and heretical.” ”
