The parishes of the Anglican Use were granted permission to celebrate certain saints not found on the universal calendar of the Catholic Church. One of the days set apart for this is June 23rd, when we keep the feast day of Ss. Hilda, Etheldreda, Mildred and All Holy Nuns. I've linked information to the names of these three amazing women, each of whom had great influence on the Church in Britain. The phrase "All Holy Nuns" includes all the great Religious women throughout the British Isles, known and unknown, who have given witness to Christ.
