II. Considering all the circumstances Anatolius might have been expected to show more modesty.
But now that these things, about which so great a concourse of priests assembled, have been brought to a good and desirable conclusion, I am surprised and grieved that the peace of the universal Church which had been divinely restored is again being disturbed by a spirit of self-seeking. For although my brother Anatolius seems necessarily to have consulted his own interest in forsaking the error of those who ordained him, and with salutary change of mind accepting the Catholic Faith, yet he ought to have taken care not to mar by any depravity of desire that which he is known to have obtained through your means. For we, having regard to your faith and intervention, though his antecedents were suspicious on account of those who consecrated him, wished to be kind rather than just towards him, that by the use of healing measures we might assuage all disturbances which through the operations of the devil had been excited; and this ought to have made him modest rather than the opposite.
For even if he had been lawfully and regularly ordained for conspicuous merit, and by the wisest selection yet without respect to the canons of the Fathers, the ordinances of the Holy Ghost, and the precedents of antiquity, no votes could have availed in his favour. I speak before a Christian and a truly religious, truly orthodox prince (when I say that) Anatolius the bishop detracts greatly from his proper merits in desiring undue aggrandizement.
