High Quality Content by WIKIPEDIA articles! Wulfstan (sometimes Lupus; died 28 May 1023) was an English Bishop of London, Bishop of Worcester, and Archbishop of York. He should not be confused with Wulfstan I, Archbishop of York or Wulfstan, Bishop of Worcester. He is thought to have begun his ecclesiastical career as a Benedictine monk. He became the Bishop of London in 996. In 1002 he was elected simultaneously to the diocese of Worcester and the archdiocese of York, holding both in plurality until 1016, when he relinquished Worcester; he remained archbishop of York until his death. It was perhaps while he was at London that he first became well known as a writer of sermons, or homilies, on the topic of Antichrist. In 1014, as archbishop, he wrote his most famous work, a homily which he titled the Sermo Lupi ad Anglos, or the Sermon of the Wolf to the English.
