O God, who through the folly of the Cross wondrously taught Saint Justin the Martyr the surpassing knowledge of Jesus Christ, grant us, through his intercession, that, having rejected deception and error, we may become steadfast in the faith. Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity  of the Holy Spirit, one God, for ever and ever. Amen

St. Justin, pray for us.
