If that is the case, then I suppose that really then makes this a non-issue. My mistake
It is perfectly possible I wrong, but my understanding takes the bolded parts to basically say that God has decreed to deliver from curse and damnation, those who he chose in Christ and to bring them by Christ to everlasting salvation. Which means (I would think) that therefore there are a remainder that are not delivered from curse and damnation through Christ chosen "before the foundations of the world were laid". I have always been under the impression that "single-predestination" is really just double-predestination in denial. I mean if it is not double, and God has chosen some to be delivered from curse and damnation... is there a third option?
I would say this shows the concept of "unlimited atonement" which I agree is not Calvinist. Otherwise I agree completely with what you have said here.
Going strictly by the TULIP acronym and the Westminster CoF the very essence of Calvinistic thought in an SoF:
Total Depravity... all are born with the inability to willfully chose God/Christ. It is impossible. WCoF 6:4:
Unconditional Election... From before the creation of the Earth, God chose by his own counsel who would attain Salvation by nothing that we have done on our own merit. (Which necessitates there are those he did not... hence automatic double predestination, just not explicitly stated.)
Limited Atonement... Our Savior Jesus Christ died for those who God chose from before the creation of the Earth. (Again, double predestination is not stated explicitly but is there by simple understanding. "If X = Y then not X = not Y.)
WCoF 3:3-5:
Irresistible Grace... God's elect will be called and drawn to him by God and will then through Grace allow them to choose God whereas before they would not have due to their Total Depravity. WCoF:
Chapter X
Perseverance of the Saints... Those who God chose as his elect, and through his Grace have accepted him, shall remain his. WCoF:
Chapter XVII
Now my understanding of Calvinism may be off slightly but that is how I have been taught it. And yes, the wording is different in the 39, but I suppose I should say it "sounds" Calvinist to me.
That actually makes far more sense to me and as I said above, this whole thing is likely a non-issue and I apologize for taking up everyone's time.
