Saint Hippolytus of Rome

O God, who has enlightened thy Church by the teaching of  thy servant Hippolytus: Enrich us evermore, we beseech thee, with thy heavenly grace, and raise up faithful witnesses who by their life and doctrine will set forth the truth of thy salvation; through Jesus Christ our Lord. Amen.
