Here, however, men will continually offer one uniform excuse for Adam – that it was not possible for him to help or avoid that which God Himself had decreed. But to establish the guilt of Adam forever, his own voluntary transgression is enough, and more than sufficient. Nor, indeed, is the secret counsel of God the real and virtual cause of sin, but manifestly the will and inclination of man. – John Calvin, ‘The Eternal Predestination of God”, in Calvin’s Calvinism, trans. & ed. by Henry Cole, 125.
