Document 2/131/56 (Haddan and Stubbs, Councils, ii, I, 255)
Pope Alexander III writes to King William I reminding him of his solicitude for William’s welfare and the hope that the king would be faithful to the apostolic see and would protect ecclesiastical liberty. But considering the situation of Bishop John of St Andrews this hope seems futile. Alexander commands William to give [largiaris] John peace and ‘security’ within twenty days of receiving this letter. Otherwise, the pontiff has commanded Archbishop Roger of York, papal legate in Scotland, to place William’s kingdom under interdict and to excommunicate William. Just as Alexander laboured to bring liberty to that kingdom, so will he work to restore its earlier subjection if William’s obstinacy continues.
