Cabarsussi was the seat of an ancient diocese [2][3][4] of which remains only the name as quasi-diocesan title, which may be granted to a pre-diocesan prelate, an auxiliary or coadjutor bishop etc.
Cabarsussi was the site of a Church Council in 393 called by a council of dissident Donatist bishops,[6] held on 24 June 393[7][8] who excommunicated their primate Primianus, the Donatist Bishop of Carthage, in favor of Maximian.
Another Donatist, Marciano, attended the Council of Carthage 411, as a strong hold of Donatism the town had no Catholic bishops at this time.
In the 6th century, Bishop Theodore, was mentioned by Victor of Tunnuna in his Chronicle of the history of the world; as a defender of the Three Chapters, Theodore was exiled to Constantinople, where he died the same day of the death of Justinian.
Finally, the last known bishop of Cabarsussi is Mustolo, who took part in the anti-monothetalism Council of Carthage of 641.
