Hi,
@Longfellow –
I started a post in response this morning, which I then erased. I'll try again ... but this might take a couple of avenues.
- Is there such a thing as Jesus's prescriptions for living?
If not that, then what is the world's
sacra doctrina about?
- Which Jesus? One of the ones in the gospels? One of Paul's Jesuses? Some historical Jesus? One of the Jesuses of Christianity or Islam or Baha'i or philosophical schools or personal philosophies (mine for example

) ?
A bit of rationalisation here:
Which Jesus? – the Jesus of the NT. That's your primary dataset.
One of the ones in the gospels? – There's only one in the Gospels.
One of Paul's Jesuses? – There's only one in Paul.
To suggest multiple Jesuses suggests an inability to reconcile the texts. That's why, in any tradition, the text goes hand in hand with commentary or, as we say, Scripture and Tradition.
(A note here, some read the Reformation's
Sola Scriptura, 'scripture alone', to mean anyone who reads scripture understands it. It doesn't, and it never did. The idea that scripture is magically 'self-explanatory' or 'self-disclosing' is refuted by scripture itself.)
The Jesus of the NT is the only one we've got.
One of the Jesuses of Christianity or Islam or Baha'i or philosophical schools or personal philosophies (mine for example

) ?
All derived from the NT.
- What does "Jesus's prescriptions for living" even mean?
Well it's your question ...
What he says in the gospels?
What other source is there?
What I think the real Jesus said if there was one?
Well if you don't think there was one, why labour the point?
How can we know what his prescriptions are, if they are not what the NT says they are?
We can't, can we? Again, if you doubt the NT, then why are you wasting your time?
... when there is so much disagreement about what it means ...
Is there?
Love God, Love your neighbour ... Does anyone disagree that's what the text says?
- What does it mean to trust his prescriptions for living? Cut off my right hand if it has an ugly scar (which it does and which I certainly do not intend to do)? If not, just pick and choose whatever I like?
Again, this is what Scripture and Tradition.
Don't cut off your hand. Don't poke out your eye, and don't put a millstone round your neck and jump into the sea. And do read texts contextually, and don't take a verse out of context and assume the most literal reading.
- Are there, or have there ever been, any people anywhere who actually do or did trust his prescriptions for living?
Yes. A few, quite notably. The vast majority, anonymously.
- Is there any reason to trust his prescriptions for living?
No-one can answer that for you.
What happens or might happen if people do it, that anyone would want to happen?
I don't understand the question.
- Is it something that he would want people to do?
- Is it something that God approves of if there is one?
