O God, by whose grace thy blessed Saint Tysilio became a burning and a shining light in the Church: Grant that we may be inflamed with the same spirit of discipline and love, and ever walk before thee in the way of perfection as children of light; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Ghost, ever one God, world without end. Amen.
¶ Or this:
Father of all, who didst call Tysilio to flee his father’s house and to dwell in solitude in the isles of the western sea: Grant that we, following his example, may be prepared to give up all that would hinder us from following in the footsteps of thy Son; to whom with thee and the Holy Spirit be all honour and glory, now and for ever. Amen.
