4 Nor let any one say, “that he who accepts martyrdom is baptized in his own blood, and peace is not necessary to him from the bishop, since he is about to have the peace of his own glory, and about to receive a greater reward from the condescension of the Lord.” First of all, he cannot be fitted for martyrdom who is not armed for the contest by the Church; and his spirit is deficient which the Eucharist received does not raise and stimulate. For the Lord says in His Gospel: “But when they deliver you up, take no thought what you shall speak; for it shall be given you in that hour what you shall speak.
For it is not you that speak, but the Spirit of your Father which speaks in you.” Now, since He says that the Spirit of the Father speaks in those who are delivered up and set in the confession of His name, how can he be found prepared or fit for that confession who has not first, in the reception of peace, received the Spirit of the Father, who, giving strength to His servants, Himself speaks and confesses in us? Then, besides— if, having forsaken everything that he has, a man shall flee, and dwelling in hiding-places and in solitude, shall fall by chance among thieves, or shall die in fever and in weakness, will it not be charged upon us that so good a soldier, who has forsaken all that he has, and contemning his house, and his parents, and his children, has preferred to follow his Lord, dies without peace and without communion?
Will not either inactive negligence or cruel hardness be ascribed to us in the day of judgment, that, pastors though we are, we have neither been willing to take care of the sheep trusted and committed to us in peace, nor to arm them in battle? Would not the charge be brought against us by the Lord, which by His prophet He utters and says? “Behold, you consume the milk, and you clothe you with the wool, and you kill them that are fed; but feed not my flock. You have not strengthened the weak; neither have you healed that which was sick, neither have you comforted that which was broken, neither have you brought again that which strayed, neither have you sought that which was lost, and that which was strong you wore out with labour.
And my sheep were scattered, because there were no shepherds: and they became meat to all the beasts of the field; and there was none who sought after them, nor brought them back. Therefore thus says the Lord, Behold, I am against the shepherds; and I will require my sheep of their hand, and cause them to cease from feeding my sheep; neither shall they feed them any more: and I will deliver my sheep from their mouth, and I will feed them with judgment.”
