C. The supralapsarian and infralapsarian interpretation of the decree:
(1) Points of agreement. Both agree:
(a) That God is not the Author of sin (supra as well as infra).
(b) That Scripture (not philosophy) is the only source of our knowledge of God's decree (supra as well as infra).
(c) That man's fall and punishment is not merely the object of God's foreknowledge but of his decree and foreordination (infra as well as supra).
(d) That faith is not the cause of the decree of election, neither sin the cause of the decree of reprobation (infra as well as supra).
The decree of election is not based on faith and reprobation is not based on sin, yet the god of Calvinism is not the author of evil? Man's fall and punishment is due to God's causing it through His decree and foreordination, but the god of Calvinism is not the author of sin?

If it is not based on faith nor sin God allows then God is the cause of a person's faith or sin, thus not giving the person the choice.
