Is God the author of evil?

Calvin dogmatically asserts that God is the author of evil. This is consistent with the assertion of Calvinism that God asserts everything.

Most Calvinists today ignore or reject this logical conclusion of their system and their most respected Bible scholar.

We deal with the evidence that Calvin taught this, the logical necessity of this position in Calvinism, and how unbiblical and blasphemous it is.
