HILARY, the Deacon, was born in Sardinia in the middle of the 4th century. He and Lucifer of Cagliari appeared at the Council of Milan before Constantius, to defend the followers of Athanasius. His remarks offended the emperor so much that he was ordered to be scourged and sent into banishment. He held that all heretics, including Arians, should be re-baptized before admission to the Catholic Church. Some writings ascribed to him are probably not his.
