Almighty God, who didst call Saint Justin Martyr to bear open witness to the certainty of those things wherein he had been instructed: Make us fearless to contend for the faith once for all delivered to thy Church, and sealed by the death of her Saints; through Jesus Christ our Lord. Amen.
¶ Or this:
O God, who through the foolishness of the Cross didst marvellously teach blessed Justin Martyr the excellent knowledte of Jesus Christ: Grant, at his intercession, that repelling the errors which beset us, we may attain unto steadfastness in the fath; through the same Jesus Christ our Lord. Amen.
