That is not a quote from Luther or Calvin, unless you are now claiming that both men wrote the bible.
I posted: "please give a quote from either or both men [Luther or Calvin or both] that states clearly and unambiguously that God is the author, creator, and cause of evil."

Calvin Commentary Isaiah 45:
"Making peace, and creating evil. By the words "light" and "darkness" he describes metaphorically not only peace and war; but adverse and prosperous events of any kind; and he extends the word peace, according to the custom of Hebrew writers, to all success and prosperity. This is made abundantly clear by the contrast; for he contrasts "peace" not only with war, but with adverse events of every sort. Fanatics torture this word evil, as if God were the author of evil, that is, of sin; but it is very obvious how ridiculously they abuse this passage of the Prophet. This is sufficiently explained by the contrast, the parts of which must agree with each other; for he contrasts "peace" with "evil," that is, with afflictions, wars, and other adverse occurrences. If he contrasted "righteousness" with "evil," there would be some plausibility in their reasonings, but this is a manifest contrast of things that are opposite to each other. Consequently, we ought not to reject the ordinary distinction, that God is the author of the "evil" of punishment, but not of the "evil" of guilt."
