I was what many would consider a hyper-Calvinist (as I believed in Reprobation). I said that Calvinism is a shallow view of the blood shed for us, an inch deep and three miles wide. The relationship we have with God is not dependent on our understanding. I never made the claim you attribute to me.Now you sound like a Hyper-Calvinist. That statement, taken by itself is a complete contradiction with your other statements claiming that repentance and faith are necessary, and that it is Calvinism that presents a shallow view of our relationship with God.
I believe that penal substitution occurred at the cross. And I think there is much truth in the other views of the atonement as also occurring. And many of those other views would seem to me to have to be concerning all men and not just the elect, thus that would be a blow to limited atonement. But that's a different subject.
I know you believe that Penal Substitution Theory accurately describes what happened at the cross. I believe that you are wrong. Instead I believe that man was reconciled to God in the person of Jesus Christ by His blood shed, that He is now the Guarantor of a new covenant representing what we will be when God judges the world. I believe the cross is completely the act of Christ and this completed our salvation in full (not a step acvomplished by the Father to make this reconciliation a possibility).
