Sorry. I forget that my explanation may have been on a thread 2 years ago. Guess I'm getting old.Jon. I don't claim any expertise in this area but honestly you owe it to explain exactly what you mean is wrong with PSA before you make a claim that meaningful discussion cannot be had here. The piece I sited above is by someone who has some credentials. I understand you do too. All I ask is that you explain what exactly you mean. To just dismiss an article like that out of hand without any reason could be an indicator of why meaningful discussion doesn't occur. I also reject the idea that you can claim 95% of something as true then say the overall theory is wrong because 5% is wrong.
Let's look at some things the Penal Substitution Theory gets right - what it shares with most other views:
1. God (the Father) was "pleased to crush Him (the Son)".
2. Christ gave Himself for us. He "was made sin for us".
3. The chastisement for our well being fell on Him, and by His stripes we are healed. He bore our sins in His body - the iniquity for us all was laid on Him.
4. Christ was forsaken (by the Father) to suffer and die on a Roman cross.
5. Without the shedding of blood there is no forgiveness.
6. Through Christ we escape the wrath to come.
There is more, but I think we get the picture - there is a lot right with the Penal Substitution Theory.
What does Penal Substitution Theory get wrong?
Here's some (about 2.5 %):
What the Theory gets wrong is what it adds to Scripture.
1. It adds that God was punishing Jesus for our sins instead of punishing us.
2. It redefines divine justice through a secular judicial philosophy of retributive justice.
3. It presents God as punishing the Righteous for the sins of the guilty to spare the guilty (which is an abomination to God).
