But even this was not deemed to be sufficient. The Pope then gave a further order that a circular letter should be sent to a number of the bishops of all nations, selected for their knowledge in theology and canon law and for their experience in the government of the Church. In this Pius the Ninth called to his aid those who were set as doctors by Christ Himself to teach the Church of God. Every bishop is, in virtue of his office, a doctor or teacher of the faith. It matters not how large or how small his diocese may be, whether it be in the Catholic unity or in partibus infidelium, whether he have a flock under his jurisdiction or not. The bishop of the least see in this is equal to the bishop of the greatest. He has been constituted a guardian of the faith by a divine commission, and his testimony as a witness is not greater or less in weight because the city over which he rules is greater or less in magnitude. It is the same in all. St Jerome says that in this all bishops are equal, and that the episcopate of the Bishop of Rome is no greater than that of the Bishop of Eugubium. We shall hereafter see the value and application of this principle.
