One of the key tenents of Calvinism is that God controls all things. Calvinists redefine “sovreign” or “almighty” to mean this and then claim the Bible backs their assertion. Contrary to this, the Bible teaches God is not the author of all things:

Jas 1:13 Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man:

What would be a Calvinist’s response to this? Well, I have asked a few in the past. Their response tends to be “no one is tempted with evil.” This is interesting because the very next verse says otherwise:

Jas 1:14 But every man is tempted, when he is drawn away of his own lust, and enticed.

The Calvinists are at a dilemma. Either they need now to explain away the plain reading of these two verses (ex. “ummm… God works through proxy so although he is the source it is not him tempting”), endorse an illogical view (“although God is the puppet-master, he is not responsible”) or reject Calvinism. Chances that a Calvinist would reject their Platonism: slim to none. When you are living high in a popular cult, you tend to ignore reality.
