October 11 is also the feast of St Ethelburga in our Ordinariate calendar. The Matins reading is taken from the Venerable Bede's Ecclesiastical History of the English People. The Clerk of Oxford gives an extended version of the same reading here.
When Ethelburga, the devout Mother of this God-fearing community, was herself about to be taken out of this world, one of the sisters whose name was Tortgyth saw a wonderful vision. This nun had lived for many years in the convent, humbly and sincerely striving to serve God, and had helped the Mother to maintain the regular observances by instructing and correcting the younger sisters. In order that her strength might be 'made perfect in weakness' as the Apostle says, she was suddenly attacked by a serious disease. Under the good providence of our Redeemer, this caused her great distress for nine years, in order that any traces of sin that remained among her virtues through ignorance or neglect might be burned away in the fires of prolonged suffering. Leaving her cell one night at first light of dawn, this sister saw distinctly what appeared to be a human body wrapped in a shroud and shining more brightly than the sun. This was raised up and carried out of the house where the sisters used to sleep. She observed closely to see how this appearance of a shining body was being raised, and saw what appeared to be cords brighter than gold which drew it upwards until it entered the open heavens and she could see it no longer. When she thought about this vision, there remained no doubt in her mind that some member of the Community was shortly to die, and that her soul would be drawn up to heaven by her good deeds as though by golden cords. And so it proved not many days later, when God's beloved Ethelburga, the Mother of the Community, was set free from her bodily prison. And none who knew her holy life can doubt that when she departed this life the gates of our heavenly home opened at her coming.
