For Luther to point to the Crucified and tell the believer that “sin is nothing but a devilish spectre and a mere fancy,” was to speak “fanatically.” Luther might write what he pleased, but here, at any rate, he was himself guilty of that fanatism of which he was fond of accusing others.[573] Schwenckfeld himself had been numbered by the preachers among the crazy fanatics. The Silesian also ruthlessly attacked the imputation of the merits of Christ by means of the _Sola Fides_. The Lutherans, even the best of them, imagine their righteousness to be nothing else “but the bare faith, since they believe God accounts them righteous, even though they remain as they were before.” “They should, however, be exhorted to search Holy Scripture and to ask themselves in their hearts whether such faith and righteousness are not rather a human persuasion, mere imposition and self-delusion ... which men invent to justify an impenitent life; not a true, living faith, the gift of the Holy Ghost ... which, as Scripture says, purifies the heart, Acts xv. ..., reconciles consciences, Rom. v. ..., and brings Christ into our hearts, Eph. iii., Gal. ii.”[574] An instructive parallel and at the same time a severe censure on Luther’s method of building up “faith” on inward assurance is afforded by Schwenckfeld’s account of the experiences and spiritual trials on which he himself had founded his faith. The preachers, insisting on the outward Word, urged that he had no right to appeal to his mere feelings; yet, as he points out, this very thing had been proclaimed from Wittenberg as the right, nay the duty of all. “In addition to all this they reject the ghostly feeling and that inward sense of the Grace of God which Luther at the outset ... declared to be necessary for salvation, writing that: ‘No one can rightly understand God or the Word of God unless he has it direct from the Holy Ghost.’ No one, however, can receive it from the Holy Ghost unless he experiences it, makes trial of it and feels it; in this experience the Holy Ghost is teaching us as in His own school, outside of which nothing is learned but all is mere delusion, words and vapouring.”[575] “How would Dr. Luther’s own gloss stand,” Schwenckfeld asks elsewhere, “which he gives on the words of the New Testament, 1 Cor. xi.: ‘Let a man prove himself,’ and where he says: ‘to prove oneself is to feel one’s faith,’ etc.? But the man who feels his faith will assuredly by such a faith—which is a power of God and the very being of the Holy Ghost—have forgiveness of sins and bear Christ in his believing heart.”[576]
