We suppose you know that the kingdom of Spain belonged of old to St. Peter, and that this right has never been lost, although the land has long been occupied by pagans. Therefore the ownership of this land inheres in the apostolic see alone, for whatever has come into the possession of the churches by the will of God, while it may be alienated from their use, may not by any lapse of time be separated from their ownership except by lawful grant. Count Evolus of Roceio, whose fame you must know, wishes to attack that land and rescue it from the heathen. Therefore we have granted him the possession of such territory as he may win from the pagans by his own efforts or with the aid of allies, on conditions agreed upon by us as the representative of St. Peter. You who join him in this undertaking should do so to the honor of St. Peter, that St. Peter may protect you from danger and reward your fidelity to him. But if any of you plan to attack that land independently with your own forces, you should do so in a spirit of devotion and with righteous motives. Beware lest after you have conquered the land you wrong St. Peter in the same way as the infidels do who now hold it. Unless you are prepared to recognize the rights of St. Peter by making an equitable agreement with us, we will forbid you by our apostolic authority to go thither, that your holy and universal mother, the church, may not suffer from her sons the same injuries which she now suffers from her enemies, to the loss not only of her property, but also of the devotion of her children. To this end we have sent to Spain our beloved son, Hugo, cardinal priest of the holy Roman church, and he will inform you more fully of our terms and conditions. 70.

Gregory, etc., to Wratislav, etc. We give thanks to omnipotent God that you have been led by your devotion and reverence for the apostles Peter and Paul, princes of the apostles, to receive our legates with kindness and treat them with the graciousness which is becoming to your majesty. Receive the assurance of our good-will in return for this evidence of your fidelity. It has not been usual for papal legates to visit your land; this, however, is partly the fault of your forefathers, as well as of our predecessors, for the dukes of Bohemia should have requested the pope to send them legates. But some of your subjects have regarded our sending of legates as an innovation, and have treated them with contempt, forgetting the word of God: "He that receiveth you receiveth me" [Matt. 10:40]; "and he that despiseth you despiseth me" [Luke 10:16]. So in failing to show due reverence to our legates, they have not so much despised them, as they have despised the word of truth.... 71. Letter of Gregory VII to Sancho, King of Aragon, 1074.
