O God, who, by the preaching of thine apostle Paul, hast caused the light of the Gospel to shine throughout the world: Grant, we beseech thee, that we, having his wonderful conversion in remembrance, may show forth our thankfulness unto thee for the same by following the holy doctrine which he taught; through Jesus Christ our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, one God, now and for ever. Amen.
