O God, Who didst vouchsafe to adorn with the grace of working miracles and the palm of martyrdom in the propagation of the true faith the blessed Fidelis, inflamed with seraphic ardour of soul, we beseech Thee, by his merits and intercession, so to strengthen us through Thy grace in faith and charity that we may be worthy to be found faithful in Thy service even unto death. Through our Lord.
