15.

 Because the bishop cannot manage the Church and supervise his flock if he is away, you should not be absent from your churches for any length of time. This was solemnly ratified by natural law and by the holy canons, especially by the decrees of the Council of Trent. The bishop should visit all the places in his diocese to protect the power of their laws when they begin to fail, either through the laziness of the ministers or through the stubbornness of the faithful. If there is a serious and necessary reason for you to leave your diocese and if it is necessary to be absent for any length of time, We ask you not to allow the Church to be weakened by the desire of her pastor. Whenever you are absent, this danger is present.
