I think the issue is that PSA assumes that redemption is a guilt equation that needs to be solved.Hi JonC, just going to target this part of the quote (the rest makes a statement that leans more to humanistic philosophy in my view).
The Lord's death is just that, innocent blood/death to solve the guilt equation. Because God desires that all men be saved, and because all men sin, the only means of eradicating our guilt is death. In a temporal context the death of the innocent animal sufficed because that death provided temporal remission, but in regards to Eternal Remission only the Death of Christ can provide remission on an eternal basis:
Hebrews 10:1-4 King James Version (KJV)
1 For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
2 For then would they not have ceased to be offered? because that the worshippers once purged should have had no more conscience of sins.
3 But in those sacrifices there is a remembrance again made of sins every year.
4 For it is not possible that the blood of bulls and of goats should take away sins.
Hebrews 10:10-14 King James Version (KJV)
10 By the which will we are sanctified through the offering of the body of Jesus Christ once for all.
11 And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins:
12 But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God;
13 From henceforth expecting till his enemies be made his footstool.
14 For by one offering he hath perfected for ever them that are sanctified.
The purpose of animal sacrifice was atonement in a temporal context. The purpose of the Cross was Atonement/Reconciliation and...Redemption. Allin an eternal context. The Lord was not just providing a remedy for the state of separation Adam created, but beyond that to an eternal union with Himself. Have you considered whether men had eternal life prior to Pentecost? Most believe Adam "died spiritually" and that is what is being corrected through Christ. The truth is that Adam's only means of "everlasting life" was the Tree of Life, and that provided only "everlasting" physical life. The Lord makes it very clear how men can have eternal life:
John 3:9-16 King James Version (KJV)
9 Nicodemus answered and said unto him, How can these things be?
10 Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things?
11 Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness.
12 If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:
15 That whosoever believeth in him should not perish, but have eternal life.
16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
If God was in Christ reconciling the world unto Himself, how many were reconciled before Christ?
God bless.
The "solution" to the "sin problem" however, is different. This is what the other positions address. It is not God punishing our sins laid on Jesus so that God can forgive us because God must punish sin else God is unjust. That, as you can probably tell with it written out, is a flawed philosophical statement. Who has to punish an action in order to forgive that action? Scripture states that upon repentance God is just and faithful to forgive. Only PSA raises an objection.
2 Corinthians 5:17-19 Therefore if anyone is in Christ, he is a new creature; the old things passed away; behold, new things have come. Now all these things are from God, who reconciled us to Himself through Christ and gave us the ministry of reconciliation, namely, that God was in Christ reconciling the world to Himself, not counting their trespasses against them, and He has committed to us the word of reconciliation.
Guilt is addressed as those in Christ are "new creatures" and the "old things are passed away" for "new things have come". There is no guilt because we are in Christ through faith, not because God punished sin in order to forgive us our sins.
I'm not addressing the passages you provided because, obviously, I agree. John 3 is a stark contradiction to PSA (when correctly correctly interpreted).
