Saint Thomas Aquinas, Doctor

O God, who hast enlightened thy Church with the wondrous learning of thy blessed Confessor Thomas Aquinas, and enriched the same with his holiness of life: grant, we beseech thee; that we may understand aright the doctrine that he taught, and also follow in all things the pattern of his conversation; through Jesus Christ our Lord. Amen.

¶ Or this:

O God, who hast enlightened thy Church by the teaching of thy servant Saint Thomas Aquinas: Enrich it evermore, we beseech thee, with thy heavenly grace, and raise up faithful witnesses, who by their life and doctrine may set forth to all men the truth of thy salvation; through Jesus Christ our Lord. Amen.
