聖達味主教
聖達味出身威爾斯皇族，母親是聖婦農恩 ( St. Nonna )。聖達味棄俗修道；晉鐸後，跟從聖保利諾 ( St. Paulinus ) 隱居，修務聖德。聖保利諾經常流淚痛哭，以致雙目失明；賴聖達味轉禱，恢復視覺。
後來，聖達味結束隱修生活，致力創建聖堂、修院。他創立的修院，生活非常刻苦，修士均須勞動，親手耕田，不能以牲畜代勞。工作時，修士們亦不忘做默禱；除非必要，絕對不准談話。三餐只能吃麵包和蔬菜。
聖達味被邀出席伯非 ( Brefi ) 教務會議，他的言論深為全場參會人士認同及支持，大家一致推舉他擔任Mynyw主教。他推進教務，建樹良多。
聖達味臨終前對修士們說：「你們喜樂吧 ! 要固守信德；我一生訓誨你們的事，務需實踐毋渝。」
公元589年，聖達味蒙主恩召；他是威爾斯的主保聖人。
祈禱
天主，你恩賜威爾斯的聖達味主教，充滿智慧，祈禱和救靈心火。求你藉他的榜樣、祈禱和轉求，使你的教會日益發揚光大。因你的聖子、我們的主耶穌基督，他和你及聖神，是唯一天主，永生永王。亞孟。
Saint David, Bishop
St. David was the son of King Sant of South Wales and St. Nonna. He was ordained a priest and later studied under St. Paulinus. Later, he was involved in missionary work and founded a number of monasteries. The monastery he founded at Menevia in Southwestern Wales was noted for extreme asceticism.
David and his Welsh monks lived a very harsh life. They worked in silence on the farms with solely manual labour. Their food was limited to bread, vegetables and water. They also devoted much of the time on prayers and intense study.
In about the year 550, David attended a synod where his eloquence impressed his fellow monks to such a degree that he was elected primate of the Cambrian Church. He was reportedly consecrated archbishop by the patriarch of Jerusalem while on a visit to the Holy Land.
St. David ruled his diocese until he had reached a very old age. His last words to his monks were: “Be joyful, brothers and sisters. Keep your faith, and do the little things that you have seen and heard with me.”
David died at his monastery in Meneviadied in 589 and he is the patron saint of Wales.
Prayer
O God, who graciously bestowed on Your
Bishop Saint David of Wales the virtue of wisdom
and the gift of eloquence, and made him an example of prayer and pastoral zeal;
grant that, through his intercession,
Your Church may ever prosper and render You joyful praise.
Through our Lord Jesus Christ,
your Son, who lives and reigns with You
in the unity of the Holy Spirit,
one God, for ever and ever. Amen.
