Jerome praised Exuperius "for his munificence to the monks of Palestine, Egypt, and Libya, and for his charity to the people of his own diocese, who were then suffering from the attacks of the Vandals, Alans, and Suevi.

In respect of his virtues and in gratitude for his gifts, Jerome dedicated his Commentary on Zacharias to him.

He had written to Pope Innocent I for instructions concerning the canon and several points of ecclesiastical behaviour.

In reply, the Pope honoured him with the letter Consulenti Tibi, dated 20 February 405, which contained a list of the canonical scriptures.

[4] The opinion of Baronius, that bishop Exuperius was the same person as the rector with the same name, is usually rejected, as the rector was a teacher of Hannibalianus and Dalmatius, nephews of Constantine the Great, and therefore from an earlier period than the bishop.
