As for Denethor, his tongue-lashing of Faramir occurs after Gandalf has let him in on the secret; and the context of course is What if Boromir had been in Ithilien? Nothing to do with the Fellowship. No-one in Gondor knew about the Ring until Gandalf's arrival in March. Remember, at the Council when Elrond relates that Isildur took the Ring, Boromir is shocked, and says expressly that this 'little' fact was completely unknown in the South. Only in Arnor and Rivendell was the truth known.

The whole notion that Denethor knew about the Ring and about the Council*, and despatched Boromir expressly to grab it for him, is an invention of Peter Jackson and his co-conspirators.


*to which no invitations were sent! Boromir in fact left Minas Tirith several weeks before Frodo ever departed Bag-end.
