On the first day of the Conference, the Donatists challenged the list of the signatures of the Catholic bishops on the document in which they had assigned their representatives. The roll call followed, in which the tribune Marcellinus, who presided, called the Catholic bishops one by one, and their Donatist counterparts were to identify them. Then the roll call proceeded in the opposite way, with the Donatist bishops identified by the Catholics.

Interventor was a presbyter, usually from another diocese, who took care of the diocese after the death of its bishop and before the election of his successor. Although Serge Lancel explains that at every occasion when the presbyters are presented at the Conference, they were "interventors", this is the first passage when it is stated explicitly.

The Donatist Bishop Adeodatus uses "Christians" for "Donatists" here.
