According to Luther, does guilt consciousness or guilt feeling comes from Satan?

Martin Luther did write quite a lot about the Devil. We also know that he was prone to severe depressions, with a particularly fearful anfechtung in 1527. He even wrote:

"If I live longer, I would like to write a book about Anfechtungen, for without them no man can understand Scripture, faith, the fear or the love of God. He does not know the meaning of hope who was never subject to temptations. David must have been plagued by a very fearful devil. He could not have had such profound insights if he had not experienced great assaults."

Now, that quote is in a book I have, which is not a critical source of quotes of Luther, as is the Catholic Criticism of Luther you quoted from. The book I have is written by a scholar, the source details given below. With regard to dealing with depressing feelings and ideas,

"Luther had two methods: the one was a head-on attack, the other an approach by way of indirection. Sometimes he would engage in direct encounter with the Devil. This particular mise en scene may amuse the modern reader and incline him not to take Luther seriously; but it is noteworthy that what the Devil says to Luther is only what one says to oneself in moments of introspection, and, what is still more significant, only the minor difficulties were referred to the Devil. In all the major encounters, God himself was the assailant. The Devil was something of a relief. Luther relished, by comparison, the personification of his enemy in the form of a being whom he could bait without danger of blasphemy. He describes with gusto some of these bouts:

When I go to bed, the Devil is always waiting for me. When he begins to plague me, I give him this answer: 'Devil, I must sleep. That's God's command, Work by day. Sleep by night. So go away.' If that doesn't work and he brings out a catalogue of sins, I say, 'Yes, old fellow, I know all about it. And I know some more you have overlooked. Here are a few extras. Put them down.' If he still won't quit and presses me hard and accuses me as a sinner, I scorn him and say, 'St. Satan, pray for me. Of course you have never done anything wrong in your life. You alone are holy. Go to God and get grace for yourself. If you want to get me all straightened out, I say, Physician, heal thyself'." Here I Stand, pp 362-3, Roland Bainton, Lion, 1987 edition

But at other times, Luther advised against any attempt to wrestle one's way through:

"Don't argue with the Devil. He has had five thousand years of experience. He has tried out all his tricks on Adam, Abraham, and David, and he knows exactly the weak spots... Eve got into trouble when she walked in the garden alone. I have my worst temptations when I am by myself. Seek convivial company, dine, dance, joke, and sing. Make yourself eat and drink even though the food may be very distasteful." (Ibid. p 363)

Then Bainton gives three rules Luther had for dispelling despondency where the Devil was appearing to attack one's faith. The second one was to get downright angry. Another idea was to seek relief through manual labor, "to harness the horse and spread manure on the fields." Bainton adds, "Luther attached great importance to his baptism. When the Devil assailed him, he would answer, 'I am baptized.'"

Whatever one may say about Luther's strategies for dealing with the way the Devil would try to destroy a person's faith in God and Christ, they were myriad! His imagination knew no bounds in how to thwart Satan's attempts to inflict a guilty conscience on that which had been cleansed by God. But please note that Luther was not dealing with a theological conundrum about where feelings of guilt come from. He was tackling head on the reality of the Devil's deceptions designed to turn a Christian from belief in Christ. He spoke from personal experience, not from dry, academic theological tomes.

The only strange thing is that it's usually people who do not even believe the Devil exists who are inclined to criticize the likes of Luther, who believed the truth of what the Bible says about the wiles of the Devil. After all the apostle James said (4:7), "Submit yourselves therefore to God. Resist the Devil, and he will flee from you." Luther certainly believed in resisting the Devil, and was not short of ideas as how to do that!

Many words are attributed to Martin Luther and not all were, actually, his. As to these words, under review, I cannot say particularly as I have not the resource to fully investigate them.

I would say that the force of the tenor of the quotation is in line with Paul's epistles to the saints in Rome and to the churches in Galatia. But the words are somewhat extravagant in regard to contemplating the commission of certain sins many times a day.

We are warned to flee certain types of sin and that those types of sin are 'not to be mentioned among the saints'. Mentioned, yes, as to warning about them, by those who are called (personally, by Christ) to do so ; but not otherwise.

So I suggest the wording is unwise and extravagant (whether they are Luther's words or whether they have been put into his mouth by someone else).

Martin Luther certainly preached, generally, in accordance with Romans and Galatians in regard to the fact that the true believer, the faithful follower of Christ, is freed from the law, by the death of Christ.

The believer is not under law, said Paul, and agreed Luther. The condemnations of law against the 'motions' of sins (that is to say the motions and desires within the flesh - but not bursting forth into flagrant activity) are to be accepted as condemnation against sin itself, which sin was eradicated in the death of Christ (who was 'made' or better still, was 'effected' sin, at Golgotha).

If 'it is no more I that do it but sin that dwelleth in me' then I, myself, am not condemned if Christ has been effected sin (itself) and has died under its curse.

Thus we who believe are 'crucified with Christ' we are 'dead indeed unto sin'. We are dead in regard to the flesh which, temporarily, still lives. We are not in the flesh but in the Spirit, if so be the Spirit of Christ dwells within us, by regeneration, by the begetting of the Father.

And we are not condemned, though sin still lurks in the flesh, and still its working may be felt.

The Devil (properly 'Daiabolos' and the 'Tempter') misinformed from the beginning and led astray at the inception of humanity placing the knowledge of good and evil before mankind, when God had forcefully stipulated that such was not the way for humanity to live. Thus was death, not life.

And the Devil continues to condemn, to tempt, to cajole, to connive, to deceive, to threaten and to hate.

But that is a different matter from the movings of the Spirit in the gift of repentance. These are matters of spiritual experience and take time to discern within one's own soul. These are not matters for the novice but for the mature in the faith to discern from their own mature experience and to express in the wisdom of eldership.

The Holy Spirit of God convicts, leads, guides, induces deep feelings of genuine contrition, expresses fundamental truth to the soul, teaches real wisdom to the mind and wholly overcomes the heart with leadings and yearnings.

Blessed is he who is led out of the movements of the Devil and into the precious movings of the Holy Spirit.

I believe Martin Luther would agree with everything I have said (from my own knowledge of his writings).

But I cannot agree with the extravagance of some of the wording and I cannot say, for sure, whether that should be attributed to Luther or not.
