What is written or taught in the bible was written before Aquinas, Augustine, or anyone else you deflect to.
I do not employ your substitute words and definitions.
I did not use the word appease.
I use the biblical term...propitiation.
Turning away the wrath of God.
PSA.is the scriptural teaching of the Covenant death Jesus accomplished.
You make claims of what you used to believe .
I and others see no evidence of your claims to holding one belief or another. You can save such posts as no one believes them to be true .
You advocate reading the bible....without understanding what you read. You could not help the Eunuch in Acts 8, so it is good God sent Philip in that day.
You would not cause the Eunuch to gain the sense of the words...you would just tell him keep reading...no need to connect the scriptural dots at all....just repeat partial sentences without explanation.
You are missing the point here.
The text of Scripture does not teach, present, or state Penal Substitution Theory. It is foreign to God's Word and foreign to the Christian faith until the Reformation.
I could help the Eunich by walking him through Scripture (through what is written) and explaining that it applies to Christ (which isin the NT Scripture).
What you would do is rely on reformed RCC doctrine that is not found in the Bible. You would rely on "progressive revelation" which would be post-Reformation teachers that tickle your ears.
How can you test Penal Substitution Theory against Scripture and still hold it? You can't...not any more than the RCC can.
What you have done is started with humanistic secular philosophy and then sought out Scripture for support. Your belief, here, is paganism read into the Bible.
Try reading Scripture without the Theory. Set it aside and at least pretend God gave His perfect and complete Word in the text of Scripture.
If you are able to set aside your own worldly wisdom it will be impossible for you to affirm Penal Substitution Theory. The question is whether you are able. You have a lot invested in the works of Calvininists. Are you even open to seek out God's Word?
