20 In the Gospel the Lord speaks, and says, “Whosoever shall confess me before men, him will I also confess before my Father which is in heaven: but he that denies me, him will I also deny.” If He does not deny him that denies, neither does He confess him that confesses; the Gospel cannot be sound in one part and waver in another. Either both must stand firm, or both must lose the force of truth. If they who deny shall not be guilty of a crime, neither shall they who confess receive the reward of a virtue.
Again, if faith which has conquered be crowned, it is of necessity that faithlessness which is conquered should be punished. Thus the martyrs can either do nothing if the Gospel may be broken; or if the Gospel cannot be broken, they can do nothing against the Gospel, since they become martyrs on account of the Gospel. Let no one, beloved brethren, let no one decry the dignity of martyrs, let no one degrade their glories and their crowns. The strength of their uncorrupted faith abides sound; nor can he either say or do anything against Christ, whose hope, and faith, and virtue, and glory, are all in Christ: those cannot be the authority for the bishops doing anything against God's command, who themselves have done God's command.
Is any one greater than God, or more merciful than God's goodness, that he should either wish that undone which God has suffered to be done, or, as if God had too little power to protect His Church, should think that we could be preserved by his help?
