I'd like to see documentation of the last claim. As an unashamed monergist, I have not seen any of the authors supporting this position "feign ignorance" on creation. Can you provide citations?If one pretends that God is not responsible for causing someone to reject Him but simultaneously espouses God's sovereignty, they seem to be missing the key link of Creation. Whether it's feigned or just a piece of cognitive dissonance is a fair enough question to ask, but it ends up with the same result. You cannot say that the Sovereign God created everything, chooses who will serve Him and then simultaneously pretend He does not cause those who do not worship Him to choose their course of faith and action.
You obviously have not heard the monogistic argument concerning theodicy - (the problem of evil). Briefly, the argument goes as follows: God decrees all that happens and in doing so has only pure motives. Men carry out that plan, often with wicked motives of their own. The two best examples are the slavery of Joseph (see Gen 50:19ff) and the death of Christ on Calvary. In both cases, God's plans are entirely holy, righteous, and just: many are saved as a result. The men who carried out God's plan were wicked and sinful and unwittingly did the will of God for their own sinful reasons. It is for those reasons that htey are judged. A third example is the use of the nations to judge Israel. They accomplished God's purpose in judging israel but committed sin in doing so because of their heart. Accordingly, they were judged. The result is that a holy God is sovereign over all and is not yet the author of evil.
Again, I ask you for citations of the "feigning ignorance" by those authors who hold a monergistic position or an admition that it is only your opinion.
