The Nicene Age

Who Lucifer of Cagliari was

Bishop of Cagliari in Sardinia, a ferocious champion of Athanasius and Nicaea who was exiled by Constantius and wrote violent pamphlets against the emperor from banishment. But his rigor curdled into schism: when the church sought to reconcile bishops who had wavered under Arian pressure, Lucifer refused all leniency, broke communion over the reconciliation of the lapsed at Antioch, and founded the short-lived rigorist sect of the Luciferians. A confessor whose zeal for orthodoxy hardened into an uncharitable schism — the mirror-image of the earlier laxist quarrels.

Also listed in bishops beyond the great sees and heretics & schismatics.
