Troparion of St Winefred tone 8
Caradog's anger struck off thy head, O pious Winefred,/
but by the prayers of the Wonderworker Beuno thy mutilated form was miraculously made whole and restored to life./
As thou didst dedicate thy life to God's service in thanksgiving for His abundant mercy,/
pray that we, never forgetting His mercy towards us, may live only for Him that our souls may be saved.
Holy Mother Winefride, pray for us !
