Pseudo-Clement

So then, brothers and sisters, after the God of truth I address to you an appeal that you may give heed to the words written, that you may save both yourselves and him who reads an address in your midst. For as a reward I ask of you repentance with the whole heart, while you bestow upon yourselves salvation and life. For by so doing we shall set a mark for all the young who wish to be diligent in godliness and the goodness of God. And let not us, in our folly, feel displeasure and indignation, whenever any one admonishes us and turns us from unrighteousness to righteousness. For there are some wicked deeds which we commit, and know it not, because of the double-mindedness and unbelief present in our breasts, and our understanding is darkened by vain desires. Let us, therefore, work righteousness, that we may be saved to the end. Blessed are they who obey these commandments, even if for a brief space they suffer in this world, and they will gather the imperishable fruit of the resurrection. Let not the godly man, therefore, grieve; if for the present he suffer affliction, blessed is the time that awaits him there; rising up to life again with the fathers he will rejoice for ever without a grief.

"Do you maintain that there is any prince of evil or not? For if you say that there is not, I can prove to you from many statements, and those too of your teacher, that there is; but if you honestly allow that the evil one exists, then I shall speak in accordance with this belief." And Peter said: "It is impossible for me to deny the assertion of my Teacher. Wherefore I allow that the evil one exists, because my Teacher, who spoke the truth in all things, has frequently asserted that he exists. For instance, then, he acknowledges that he conversed with Him, and tempted Him for forty days. And I know that He has said somewhere else, 'If Satan casts out Satan, he is divided against himself: how then is his kingdom to stand?' And He pointed out that He saw the evil one like lightning falling down from heaven. And elsewhere He said, 'He who sowed the bad seed is the devil.' And again, 'Give no pretext to the evil one.' Moreover, in giving advice, He said, 'Let your yea be yea, and your nay nay; for what is more than these is of the evil one.' Also, in the prayer which He delivered to us, we have it said, 'Deliver us from the evil one.' And in another place, He promised that He would say to those who are impious, 'Go into outer darkness, which the Father prepared for the devil and his angels.' And not to prolong this statement further, I know that my Teacher often said that there is an evil one. Wherefore I also agree in thinking that he exists. If, then, in future you have anything to say in accordance with this belief, say it, as you promised."
