David of Wales
Bishop and Monastic Reformer
Sanctified Life
Approx. 500 AD — Approx. 589 AD
Caerfai, Pembrokeshire, Wales
Also Known As
"Do the little things in life. (Gwnewch y pethau bychain mewn bywyd)"
David of Wales (Dewi Sant) was the patron saint of Wales and its leading sixth-century monastic reformer — a bishop whose austere rule and preaching shaped the Welsh Church for centuries. At the Synod of Brefi, the ground rose beneath him as he preached and a white dove settled on his shoulder. His final words to his monks were simple: 'Do the little things in life.'

Life & Times
Early Life
Born around 500 AD at Caerfai on the Pembrokeshire coast, David was the son of Non — herself venerated as a saint — and grandson of Ceredig ap Cunedda, king of Ceredigion. Educated at the monastery of Hen Fynyw and later under the scholar Paulinus, he absorbed a rigorous monastic tradition spreading across the western shores of Britain and went on to found multiple communities across Wales before settling on his defining work at the edge of the Pembrokeshire sea.
Turning Point
Around 540, the Synod of Brefi was convened to confront the resurgent Pelagian heresy. When the assembled bishops struggled to make themselves heard, David was invited to speak. As he preached, the ground rose miraculously beneath him — forming a small hill — and a white dove descended and settled on his shoulder, a sign read immediately as divine confirmation of his authority. According to tradition, David was subsequently offered the see of Jerusalem and declined it, choosing to remain with his own people.
Legacy
David established his most important monastery at Meneva in the Vale of Roses (Glyn Rhosyn) — the site where Saint David's Cathedral still stands against the Pembrokeshire sky. His rule was severe: monks pulled plows themselves rather than using oxen, subsisted on bread, salt, herbs, and water, and gave their evenings entirely to prayer, reading, and writing. He was known for miracles — restoring sight to the blind and, according to tradition, raising a child from death. He died around 589, his final sermon leaving behind the maxim that became Wales's most cherished spiritual inheritance: 'Be joyful, keep your faith. Do the little things.' Canonized by Pope Callistus II around 1120, his feast on March 1 has been Wales's national day for over a thousand years.

“Be joyful, and keep your faith and your creed. Do the little things that you have seen me do and heard about.”
Final Sermon: Gwnewch y Pethau Bychain
David's last address to his monks, delivered days before his death around 589 AD. Its closing words — 'Do the little things in life' — became Wales's most enduring spiritual maxim and remain central to Welsh Christian identity today.
O Saint David, Dewi Sant, patron of Wales — you were offered the see of Jerusalem and chose Pembrokeshire, because the people God gave you were enough. You built a monastery at the edge of the sea and filled it with monks who pulled their own plows, ate bread and water, and gave their evenings to prayer. You preached until the ground rose to hold you up, and a white dove came down and rested on your shoulder. And when you were dying, you asked only this: be joyful, keep your faith, and do the little things. Help us to believe that the little things are enough — that faithfulness in the ordinary is the form holiness takes in most of our lives. Pray for Wales. Pray for poets. Pray for all who love the land they were given and stay with it. Amen.
