It was after he became legate, and no doubt in virtue of his legatine commission, that he issued a treatise which may be regarded as the programme of the Reformation. It is entitled _De Statu Ecclesiae_. Of this a fragment, including its earlier chapters, is still in our hands.[38]
Before giving a slight summary of its contents I must mention that it is addressed "to the bishops and presbyters of the whole of Ireland," and that Gilbert declares that he wrote it at the urgent request of many of them. In this statement there may lurk an element of exaggeration. But behind it there lies at least so much truth as this. A considerable body of the clergy had approached the newly made legate, and requested his instruction regarding the proper constitution of the Church--for such is the subject of his tract; and that implies that the Romanizing movement was no longer in its infancy. There were many bishops and presbyters who had become dissatisfied with the old Irish method of Church government. They desired to bring it into conformity with that of the Roman Church. But they were in some uncertainty as to the nature of the changes that should be made, and so they asked Gilbert to give them authoritative counsel.
In reply to their petition, with the aid of an elaborate diagram, he sketched as follows the organization of a properly ordered Church.
The bishops, he tells us, and others of higher rank in the ministry belong to the general Church, as distinct from particular churches. The priest is the highest officer in a particular church. It is the primary duty of every priest to serve and obey his bishop with all humility. For by the bishops particular churches are ruled. To each bishop are subject all the churches within his jurisdiction. And this applies as well to monastic establishments as to parishes. The head of each parish is a priest, the head of each monastery is an abbot, who is himself a priest. The bishop has a pontifical church, in which is his see (_sedes_), and of which he is the head. From it he governs the inferior churches. A bishop can perform all the offices of a priest, but he has seven functions peculiar to himself: to confirm, to bless, to absolve, to hold synods, to dedicate churches and altars, to consecrate the ornaments of churches, to ordain abbots and abbesses and the secular clergy. Gilbert's diagram represented the bishop as ruling two churches; but he explains that this is to be interpreted figuratively. A bishop may have as many as a thousand churches within his jurisdiction: he must have at least ten.
