O God, who didst vouchsafe to honour blessed Fidelis, inflamed with a seraphic ardour of spirit in the propagation of the true faith, with the palm of martyrdom and glorious miracles: we beseech thee, by his merits and intercession, so confirm us by thy grace in faith and charity, that we may deserve to be found faithful in thy service, even unto death.
