II. Following the examples of his predecessors he nominates Anastasius Metropolitan of Illyricum.
Now therefore, dear brother, that your request has been made known to us through our son Nicolaus the priest, that you, too, like your predecessors, might receive from us in our turn authority over Illyricum for the observance of the rules, we give our consent and earnestly exhort that no concealment and no negligence may be allowed in the management of the churches situated throughout Illyricum, which we commit to you in our stead, following the precedent of Siricius of blessed remembrance, who then, for the first time, acting on a fixed method, entrusted them to your last predecessor but one, Anysius of holy memory, who had at the time well deserved of the Apostolic See, and was approved by after events: that he might render assistance to the churches situated in that province whom he wished kept up to discipline.
Noble precedents must be followed with eagerness that we may show ourselves in all things like those whose privileges we wish to enjoy. We wish you to imitate your last predecessor but one as well as of your immediate predecessor who is known equally with the former to have both deserved and employed this privilege: so that we may rejoice in the progress of the churches which we commit to you in our stead. For as the conduct of matters progresses creditably when committed to one who acts well and carries out skilfully the duties of the priestly position, so it is found to be only a burden to him who, when power is entrusted to him, uses not the moderation that is due.
