Please pay close attention to this from the Westminster Confession, which is simply a dodge. "God from all eternity, did, by the most wise and holy counsel of His own will, freely, and unchangeable 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.
Another way of saying the above is that God decreed (predetermined, unchangeably ordained) everything that happens on earth, yet He cannot be held responsible for all the sin an evil. So how is that even possible? Does the Bible even suggest such a thing? There is a huge difference between God ALLOWING sin and evil to exist and God UNCHANGEABLY ORDAINING all the sin and evil. And we know that God allows sin, evil, wickedness, and iniquity for a season, but not forever.
It is a real shame that the Westminster Confession failed to present Bible Truth and Gospel Truth as found in the Bible. Had those men who compiled it refused to be swayed by Reformed Theology, every Christian could have given full consent to that document. People should also understand that (at least) the conservative Presbyterian churches expect their members to give full consent to the Westminster Confession. Possibly the Reformed Churches also. The liberal Presbyterians probably don't care one way or another.
