Once elected, his consecration was delayed for five years while he fought attempts by the Archbishop of Canterbury to assert primacy over York.Thurstan was the son of a canon of St Paul's in London named Anger, Auger or Ansgar,[b] who held the prebend of Cantlers.[6] Early in his career, Thurstan held the prebendary of Consumpta per mare in the diocese of London,[7] and served both William Rufus and Henry I as a royal clerk.[11] The Archbishop of Canterbury, Ralph d'Escures, refused to consecrate Thurstan unless the archbishop-elect made a profession of obedience to the southern see.[13] Thurstan refused to make such a profession,[12] and asked the king for permission to go to Rome to consult Pope Paschal II.Henry I refused to allow him to make the journey, but even without a personal appeal from Thurstan, Paschal decided against Canterbury.[15] Enraged at this, the king refused to allow the newly consecrated archbishop to enter England, and Thurstan remained for some time on the continent in the company of the pope.[12] While he was travelling with the pope, he also visited Adela of Blois, King Henry's sister, who was also Thurstan's spiritual daughter.At the time the pope's approval was not needed for sainthood; the monks at Pontefract exhumed his body two years after his death and, finding it well-preserved, acclaimed him as a saint.Thurstan and the baronage of Yorkshire had been partners in a common enterprise, their security in this world and their salvation in the next, and to all aspects of his role he had shown a complete commitment."
