For if Man is not responsible for his acts, and therefore cannot sin against God, there is no foundation for the doctrines of the Fall, the Sin, the Curse, or the Atonement.
If Man cannot sin against God, and if God is responsible for all Man's acts, the Old Testament is not true, the New Testament is not true, the Christian religion is not true.
And if you consider the numerous crimes and blunders of the Christian Church, you will always find that they grew out of the theory of Free Will, and the doctrines of Man's sin against God, and Man's responsibility and "wickedness."
St. Paul said, "As in Adam all men fell, so in Christ are all made whole." If Adam did not fall St. Paul was mistaken.
Christ is reported to have prayed on the cross, "Father, forgive them, for they know not what they do."
That looks as if Jesus knew that the men were not responsible for their acts, and did not know any better. But if they knew not what they did, why should God be asked to forgive them?
But let us go over the Determinist theory again, for it is most important.
If God is responsible for Man's existence, God is responsible for Man's acts.
The Christians say Man sinned, and they talk about his freedom of choice. But they say God made Man, as He made all things.
Now, if God is all-knowing, He knew before He made Man what Man would do. He knew that Man could do nothing but what God had enabled him to do. That he could do nothing but what he was foreordained by God to do.
