As soon as you are picking and choosing, how are you adhering to any supposed wisdom provided by the divine?

I'd suggest using your best judgement - no one here is advocating for orthodoxy. Times have changed over the last 2-3000 years, and things that were once practical may not be anymore.

I think you might be assuming that the only interpretation of religious text is that they are all-or-nothing affairs, across the board. One of the core tenets to Christianity is the recognition that everyone is going to sin (or not "adhere to the supposed wisdom of the divine" as you put it) and that they will still be forgiven.
