I suppose if you are a complete hyper-Calvinist and totally disavow any notion of free will then you have no need of any “synthesis”. From the standpoint of traditional logic, this is probably the strongest position. For the rest of us, free will and omniscience make for dichotomous bedfellows. Of course, the hyper-Calvanist still has scripture to deal with.
And there’s still the issue of the Trinity and how God being both one and three relates to traditional logic.
It should be noted that I think traditional logic is one of the sharpest tools in the Christian’s bag. I’m just thinking out loud, that’s all.
