Sorry but Calvinism proclaims God ordains (predestines) whatsoever comes to pass. This is presented in a well published confession. For you to claim otherwise is to run away from the actual doctrine of Calvinism.
I did not say God is the author of sin, but that would be the result of God ordaining sin. Again, for you to deny the obvious is disheartening. Unless we stick to the truth, no communication is possible and the devil wins.
Finally did I say you or anyone opposes a "free will salvation?" Nope I said fallen humanity has a limited autonomous will. See post #74.
If you want to dispute what Calvinism proclaims, provide a link that says Calvinism does not proclaim God ordains whatsoever comes to pass...
God Ordains Whatsoever Comes to Pass
P.S. God's sovereignty does not require that God predestines everything, only that He either causes or allows everything.
