are pleased to obey the Apostle’s precepts, where he says, “See that no one deceive you with philosophy and vain seductions of men.” For according to the same Apostle, “if I build up those things which I destroyed, I prove myself a transgressor,” and subject myself to those conditions of punishment which not only the authority of Prince Marcian of blessed memory, but I myself also by my consent have accepted. Because as you have justly and truthfully maintained perfection admits of no increase nor fulness of addition. And hence, since I know you, venerable Prince, imbued as you are with the purest light of truth, waver in no part of the Faith, but with just and perfect judgment distinguish right from wrong, and separate what is to be embraced from what is to be rejected, I beseech you not to think that my humility is to be blamed for want of confidence, since my cautiousness is not only in the interests of the universal Church but also for the furtherance of your own glory, that under your reign the unscrupulousness of heretics may not seem to be advanced and the security of catholics disturbed.
