Slander!
No Calvinist ever said that! Never!
Yes, no Calvinist have directly said this exact wording.
This is just a summary of Calvinist’s doctrine of predestination.
God from all eternity did by the most wise and holy counsel of his own will, freely and unchangeably ordain whatsoever comes to pass; yet so as thereby neither is God the author of sin; nor is violence offered to the will of the creatures, nor is the liberty or contingency of second causes taken away, but rather established.
— The Westminster Confession of Faith (1643)
While the word “God the author of sin” is debatable by many within Calvinist themselves, most Calvinist will agree that all and everything is ordained by God’s will.
So, whatever i do and did, it’s already ordained by God.
So, according to Calvinism, Leon Trotsky, Adolf Hitler, Pol Pot, Mao Zedong, Joseph Stalin, Vladimir Lenin, all their murder on millions of men is God’s ordained.
All the mass shooting is God’s ordained. God’s most wise and holy counsel of his own will.
All suicide bombers is God’s ordained. God’s way.
These are the real slanders against God’s character. God do not sin and will never have anything to do with sin, especially God will never ordained anyone to sin.
What the bible tell us?
Isaiah 55
7 Let the wicked forsake his way, and the unrighteous man his thoughts: and let him return unto the LORD, and he will have mercy upon him; and to our God, for he will abundantly pardon.
8 For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD.
9 For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.
