Troparion of St Deiniol the Younger
Tone 8
Being preserved from martyrdom at the hands of the warlike Ethelfrid,
thou didst persevere in thy missionary labours, O Father Deiniol.
Wherefore we entreat thee to pray to God for us
that, being firm in the faith, we may be found worthy of His great mercy.
