To calm the anxiety of the people over the imperial decree, he lays his answer before them, and adds that he did not go to the consistory, because he was afraid of losing the basilica. Then, first challenging his opponents to a discussion in the church, he says that he is not terrified at their weapons; and also, after recalling his answer on the subject of the sacred vessels, declares that he is ready for the contest. The will of God, he maintains, cannot be frustrated, nor can His protection be overcome, yet He is ready too to suffer in His servants.
Since he has not already been taken before this, it is plain that the heretics are causing this disturbance for no reason whatever. Next, after applying Naboth's history and Christ's entry into Jerusalem to the present state of affairs, he censures Auxentius' cruel law, answers the Arians' objections, and states that he will gladly discuss the matter in the presence of the people. Auxentius, he adds, has been already condemned by the pagans, whom he had chosen to sit as judges, as he had been condemned by Paul and by Christ.
The heretic had forgotten the year before, when he had made the same appeal to Cæsar; and the Arians, in stirring up ill-will against the servants of Christ, are much worse than the Jews: for the Church does not belong to Cæsar, but displays the image of Christ. Then adding to these a few more words on his answer and his hymns, he declares that he is not disobedient, that the Emperor is a son of the Church, and that Auxentius is worse than a Jew.
