Leaving aside the question of the Julian Kalendar for the time being, today is the feast of St Ethelwold of Winchester, who was a friend and contemporary of St Dunstan, and one of his disciples at Glastonbury. Around A.D 950 he founded a strict Benedictine monastery at Abingdon and in 963 St Dunstan consecrated him Bishop of Winchester. He went on to found many monasteries throughout England, notably Ely and Peterborough. He died in 984.
He is not celebrated in the Universal Church, so you will look in vain for him in the Ordo, but I am very much in favour of local kalendars personally, even local liturgical books. In my opinion, not every saint in the Universal Kalendar is worthy of universal veneration, and many saints of local status are even holier, wiser and more heroic than many of these (not that I am any judge of personal holiness). St Ethelwold's Collect, very fine in my estimation, runs as follows:
O God, on this day You caused new light to shine forth among the glorious stars of heaven for the English people in the brilliance of Your holy bishop Ethelwold. Humbly we beseech Your mercy that as we recognise his teaching and authority throughout our land, so may we be formed by his example and protection. Through Our Lord Jesus Christ Your Son, who lives and reigns with You in the unity of the Holy Ghost, unto the ages of ages. Amen. (From the Portiforium of St Wulfstan).
The above photo is of the old arches of Abingdon Abbey, a disheveled vision of that which has been left far behind by the flowing streams of Time. I wonder what Liturgy was like there?
