The Ante-Nicene Church

Who Sidonius was

One of four Roman confessors who had gone over to Novatian and then came back, exposing what they had been told to get them there. Cornelius names him in the letter to Fabius of Antioch that Eusebius quotes at length — evidence that the Novatianist schism at Rome lost people as fast as it gained them.

Verified single attestation

Named once in Eusebius’ Ecclesiastical History; no other ancient source names him.
