Change is good. We shouldn’t stay with the errors of the past. But some change-lovers go too far: they want to change the unchanging Word of God. It’s value lies not in an evolving interpretation subject to winds of change. It’s value lies in its unchanging nature.
You can’t modify God’s injunctions, no matter how much you would wish to see otherwise. There are good, profound and correct reasons that some sins cannot be taken off the sin list. Christianity is not like building code or constitutional updates. God doesn’t need to rewrite the code to patch vulnerabilities.
The beauty of the Word of God is its perfection, its immutability, its eternity. What was true thousands of years ago is still true today. It’s universal. There are things that are difficult for us moderns to understand. I’m sure the ancients felt the same way — maybe towards the things that we really do understand.
