Circumventing Paul requires copious misalignments in other texts. The topic is reinforced by Peter and references the old testament for a reason. He's grounding the principle in its initial intent and providing an example of its expression.
All scriptures are good for teaching. But we don't do everything written in there like many teachings from the Old testament.
Punishments for certain misconduct is death. Ironically, Jesus didn't say He came to abolish any law. When Jesus stepped in to save an adulterer from being stoned to death, He did not explicitly say the law is no longer in effect, He only implied those who are executing the judgement (the people who surrounded the woman to stone her are probably guilty of bigger sins than the adulterer they're about to stone to death.
Peter is generally supportive of Paul but in one passage, he described some of Paul's teachings as "not making sense at all" or nonsensical, jibberish if you try to understand it from its Greek studies. English translations tend to 'water down' the extent of what is being said in the more original Greek translation of the New Testament because Greek is a context-rich language.
Even Paul himself said he adapted himself to the culture of his audiences (1 Corinthians 9:19-23).
If you're carefully studying Paul's epistles, you will notice in some of his writings, he speaks to those not possessing the character of a righteous person are unsaved. So you still need to actually stop sinning or at least try your best not to sin. Apparently contradicting Paul's other statements that salvation is by faith alone.
Yet, they are not contradictions. Paul is merely speaking in a way that his audiences of various cultures will understand and break down the barriers of the mind that has blocked their understanding of the truth.
I'm not trying to filter out the easy vs hard teachings in the Bible.
I'm a man and who wouldn't want a perfectly submissive wife and not just a submissive wife but a wife who is actually happy submitting to her husband? I'd love that!
I really do but after having deeper studies of the Bible and knowing Paul and the other apostles much better now, I don't think it is what is being taught in the Bible.
You have pay very close attention to whatever you're reading. Never adopt any biases when reading if you must see the truth or what is truly being said in the Bible.
The people who tried to eliminate, destroy the Bible may surprise you that it's not for the reasons you're expecting and at some points in history, the Orthodox Christianity is involved. This is why never read the Bible with any bias because often that biases isn't yours. It did not originate from your mind but pressed into your mind by someone or something else. Your parents, even your church, the system, the world.
