The bishop suffered this fate by refusing to collect Peter's Pence, a tax of 1/10 of the income of every freeman.
This tax was encouraged by the Papacy, and had a strong history in the Scandinavian world.
His predecessor Aindréas had allowed it, but John stood up for the complaints of the peasantry.
John certainly survived the attack, although Earl Harald and the people of the Earldom suffered the consequences, as Pope Innocent III and King William of Scotland brought down their wrath on the province.
