The Councils of Carthage, or Synods of Carthage, were church synods held during the 3rd, 4th, and 5th centuries in the city of Carthage in Africa. The most important of these are described below.
In May 251 a synod, assembled under the presidency of Cyprian to consider the treatment of the Lapsi, excommunicated Felicissimus and five other Novatian bishops (Rigorists), and declared that the lapsi should be dealt with, not with indiscriminate severity, but according to the degree of individual guilt. These decisions were confirmed by a synod of Rome in the autumn of the same year. Other Carthaginian synods concerning the lapsi were held in 252 and 254.
Two synods, in 255 and 256, held under Cyprian, pronounced against the validity of heretical baptism, thus taking direct issue with Stephen I, bishop of Rome, who promptly repudiated them. A third synod in September 256, possibly following the repudiation, unanimously reaffirmed the position of the other two. Stephen's claims to authority as bishop of bishops were sharply resented, and for some time the relations of the Roman and African sees were severely strained.
Around 345–349 under Gratus a synod of orthodox bishops, who had met to record their gratitude for the effective official repression of the Circumcelliones (Donatists), declared against the rebaptism of any one who had been baptized in the name of the Trinity, and adopted twelve canons of clerical discipline.
The Council of Carthage, called the third by Denzinger, issued a canon of the Bible on 28 August 397. The primary source of information about the third Council of Carthage comes from the Codex Canonum Ecclesiæ Africanæ, which presents a compilation of ordinances enacted by various church councils in Carthage during the fourth and fifth centuries. In one section of this code the following paragraph concerning the canon of Scripture appears.
