nostr:npub16xc333smpl92c0v730404zae5eyue6fpw44gl47zrj5hkjv9kwxsj54jqm looks interesting. I just realised my language was imprecise. From a Catholic perspective "to do: read the Deuterocanonical books".
I haven't read outside the protestant cannon much, I read the Didache and loved it. I started the Shephard of Hermas but didn't finish.
