22 Therefore, Auxentius is cast out. Mercurius is shut out. The portent is one, the names are two! That no one might know who he was, he changed his name so as to call himself Auxentius, because there had been here an Arian bishop, named Auxentius. He did this to deceive the people over whom the other had had power. He changed his name, but he did not change his falseness. He puts off the wolf, yet puts on the wolf again. It is no help to him that he has changed his name; whatever happens he is known. He is called by one name in the parts of Scythia, he is called by another here. He has a name for each country he lives in. He has two names already, and if he were to go elsewhere from here, he will have yet a third. For how will he endure to keep a name as a proof of such wickedness? He did less in Scythia, and was so ashamed that he changed his name. Here he has dared to do worse things, and will he be ready to be betrayed by his name wherever he goes? Shall he write the death warrant of so many people with his own hand, and yet be able to be unshaken in mind?
