Yes, thank you, I guess you are right! (I wanted to keep my post short following my very long one immediately before, but I kept it short sloppily). And by Protestant, of course I meant the non-Catholic western churches that emerged after the Reformation. I did not comment on the eastern Orthodox position(s).
I was specifically addressing the meaning of 'knowledge' in the post to which I was responding. Of course predestination, pre-ordination, and 'foreknowledge' (in the technical sense in which I was using it) are all interconnected and I believe I did reasonable justice to the Calvinist position (independent of whether I agree with it or not). I believe Calvin would himself track his view back (through Luther) to Augustine in the latter's stand against Pelagius who was to be declared a heretic.
Of course Augustine's idea that God is proactive in salvation was nuanced by Cassian and, much later, by Jacob Arminius. Yes, God was proactive but not monergistically. Man had to play his part, synergistically. This is a very different view within Protestantism and, yes, Calvin will be turning in his grave!
I suppose I sloppily passed over this Protestant synergism, seeing it as a slight variation of Catholic synergism. In my view, neither forms of synergism can support the predestination or pre-ordination or foreknowledge in the robust form in which I believe it appears in Rom 8's Golden Chain. Those concepts require monergism
But yes, there remain many Protestant attempts to reconcile synergism with predestination. One could be rendered 'justification by faith but sanctification by works' (perhaps unfairly seen as 'Jesus gets you in, your job to stay in', ie don't apostasize). Then there is one that portrays 'the perseverance of the saints' as a prescription not a promise (perhaps unfairly seen as 'Do your best, and Jesus will make up the rest', but be complacent). In my view, both are crypto-synergistic and cannot support the predestination that is intended to bring assurance
However if I have omitted some or not done justice above, I'd love to hear more from you
Forms of synergism will always remain because they are often seen as the best way of avoiding the charges that God is (i) arbitrary in election, and (ii) potentially the author of evil. Paul addresses arbitrariness in Roms 9. I don't think his vivid 'potter' analogy need be taken as a defence of arbitrariness, but it certainly stands as a rebuke to us when we apply human justice to God. He is after all the author and definer of 'fairness' and any sense of it that we have comes from Him and is no doubt corrupted by us.
The charge that God is the author of evil is addressed in Job, even if not to our human satisfaction. Questions of theodicy are all track back to the question of why did God even allow for a Satan and a Fall. On this issue, we are normally prepared to accept God's unfathomable sovereignty and His unfathomable goodness, so there is no great merit in quibbling later on about election. Jesus made it clear that questions of theodicy (the tower of Siloam) are really opportunities for theophany (that God might be seen)
Apologies - this has turned out to be a long one as well !
