own motion not in compliance with any petition offered to us on this subject, but of our spontaneous liberality, foresight, and certain knowledge, and from the plenitude of apostolic power, considering the letters of Nicholas and of Calixtus, our predecessors, the articles aforesaid [i.e The Treaty of Alcáçovas], as valid and acceptable, do by apostolic authority and tenor of these presents, approve and confirm them and everything contained in them and secure them by the protection of this present writing, decreeing that they, all and singular, ought to possess full authority and be observed forever. And moreover, by our apostolic writings and on our motion and knowledge aforesaid, we command our venerable brothers, the bishops of Evora and of Silves and of Portugal, that they themselves, or two or one of them, by himself, or another or others, solemnly publishing each of the aforesaid letters and the article, where and when it shall be necessary, and assisting with efficacious protection the said King and Prince of Portugal and their successors, in all and singular the aforesaid, shall not permit the said king and prince and their successors to be molested or even hindered, contrary to the aforesaid, or any part of it, by anyone of whatsoever rank, position, degree, or condition he may be, restraining in our name all persons soever who obstruct, hinder, oppose, or rebel against the aforesaid, by ecclesiastical censures or other legal remdies, without permitting appeals, all [apostolic constitutions] to the contrary notwithstanding, even though an indult shall have been granted by the Apostolic See to any persons, jointly or singly, declaring them to be exempt from interdiction, suspension, or excommunication by apostolic letters that do not make full and express and verbatim mention of the said indult. Let no one, therefore, infringe or with rash boldness contravene this, our confirmation, approbation, reinforcement, regulation, and mandate. Should anyone presume to do so, be it known to him that he will incur the wrath of Almighty God and of the blessed apostles, Peter and Paul.
Given at Rome, at St. Peter's on the twenty-first day of June, in the year of the Incarnation of our Lord, one thousand, four hundred and eighty-one, in the tenth year of our pontificate.
